Why Linux

I like the GUI better, as well as the font rendering.

i dont know!!
but for my limited experience in linux you can make it dance if you got the skill.
i use it as a faster/safer internet machine. my family got used to it coming form windows and MacOS, gave them similar GUI. and i can troubleshoot linux for them

I can write a big list of diferences between Linux and Windows but i tink u need google it. Cuz have lot diferences.
I not blame you if u like use more windows than linux, Microsoft pay lot ppl to make u use windows. But in summary Linux have a very robust OS, lot less bugs. You have many Desktop managers, and can choose what pleases you . You can customize everything.

Windows have a bether video card suport, and more games suported.. I tink is only it the Windows advantages.

Personally i use Windows to play and Linux to work. Some games run natively on linux then this games i play in linux ^^
( i realy not know mutch about MacOS, but Linux and MacOS are Unix based )

It's free.

much faster because of lower system requirements

There's a very small userbase for it, which results in very few games and other software being ported to it, which results in a very small userbase. It's going to be a self perpetuating cycle for a while.

heard about bloatware?
for example, let's think that i am dumb and all i need is to surf in internet for some lulz and play games... i don't need graphical editors, text editors, audio players and such stuff that aren't related to surfing and games, but when i install windows 8.1 i got 20 Gb of my harddisk space consumed by unnecessary stuff that i won't use... and this hellish metro ^^
btw, same thing is now in ubuntu, which i left cause they started to do similiar things with programs which i liked... after another distroupgrade they just removed apps which i was using by another same apps...
so i moved to another linux distribution... and if i need some program i simply can install it, but for archlinux i needed some efforts to be able to maintain it...
simple as it is... if you want just to use pc as gaming rig or surfing browser, so windows is ok, but if you want to tune os for yourself then linux.
P.S. i still have windows 8.1 installed for moments when i need to play games, though developers releasing more and more games for linux :) (thanks to steam i guess)

because it's free

it's free, more customizable, not bloated with crap, and you have various distros and desktop environments to choose from.

P.s: check ElementaryOS, I'm sure you'll like it.

You can make a computer do almost anything with linux IF you are willing to put in the work. There are many things that you just cannot do in windows, raw network card control is the first thing that comes to mind. MacOS is actually based in BSD, an operating system very similar to linux but is heavily locked down.

All of this said lunux can be VERY hard to work with if you are not tech savvy, I've had cases where is taken my months to figure out a system error. Once you have everything worked out it almost unstoppable but it WILL take a long time to get there.

Free and easier to update. I can run one command on Linux and every program, driver, part of the system will be updated for me. On Windows I have to try and update every program individually and updating all your drivers is a pain in the ass (or even finding what version you're currently using or what needs updating).

To be honest some of those things are not right.
1.Easier update - depends what linux we are talking about, what software etc.
2.much more stability - that depends on hardware You have, linux version and so on.
3.viruses - that is idiotic thin to talk You have to go on root and run virus. if ur typical user you will never have one. i have no viruses on windows 7 either.
4.driver problems - ex. some of graphic cards have problem and then You end up with 12 screens with strange resulotion on your desktop. i saw it on g105 ( that problem was on nvidia graphics , with the ubuntu driver was ok but no acceleration )

The talk about is linux really better is not important. Ive been attending linux users group in my town for several years, using different distros from ubuntu , debian to gentoo and arch. Not every distro is for normal user, i am programmer so i work on linux watch movies other stuff , but if i play games i dont try to be stubborn and try my games to work on linux i just relog on windows.

I prefer linux for databases (performance and costs). Anything but things who need user interaction in a pc.

Its good in cellphones (Android is based on the Linux kernel), also for porformance and costs since it doesnt require drivers or another weird requerimenst for final users.

free, faster, doesnt take much space on hdd, more stable than winfail, some games runs better on it (windfail games with wine), also you can easily count the number of malware's on linux http://en.wikipedia.org/wiki/Linux_malware#Threats :)

BECAUSE WHY NOT?

"the internet is a mess" Yes, there it is. The point where you should stop thinking about it too much. Go to actual websites (not forums) for comparisons to get REAL facts.

the main advantage I see is the package managers, almost all the programs you need installed from a repository instead of searching for them, dependencies automatically calculated and isntalled, and also kept updated witouth each program wanting a tray application to update itself.

First thing it's the price. Also, you know Android is Linux?

Best for daily use unless you're a professional of sorts and need certain software. Fast, reliable, configurable and secure.

makes it easier to write complex command chains

Hands down best thing about Linux is the ability to control it. I work with enterprise environments where we have to lockdown Windows for very specific uses (users can only use our alternative shell). Every time a Windows update rolls through, we have little other than Automated Tests to check if something they did to protect normal desktop users hasn't obliterated one of our protections to prevent the users from reaching a Windows Shell. We work with a very sensitive user base and being on the Windows/ .Net stack makes it hard to manage these devices as our customers expect. We are working on Linux version of our setup because we can turn off "Security" features that hinder our ability to limit access to certain features.

Heck for that matter we can uninstall those features altogether. linux offers this freedom and with advances like Flatpak, a ubiquitous platform similar to windows where the base operating system can be managed by a distributor but modified by developers and/or users.

EDIT: sorry saw it at the top and didn't think to check more than 2 posts up on date :(

For me I can do lots of evil things with it using some opensource (pronounced free) software on it. Sometimes there is no windows free counterparts for my purposes.
