Your favorite controller for PC gaming? (poll inside)

I have a couple of XBOX 360 and they're ok. I also have a first generation Logitech Rumblepad which fits my large hands much nicer but only works with very few games. I just ordered a Steam controller to see if I can finally find a gamepad that I really like and that works with all games. In any case, I don't expect it to be better for anything that works fine with keyboard + mouse (or better yet, Logitech G13 + mouse, which is my preferred combination).

Nvidia Shield Controller

I have a third-party knockoff 360-like controller and it's... bearable. It's pretty good for action games. But first-person games, RPGs and the like feel much better to me if I play them with keyboard and mouse. And especially simulators, because a controller just doesn't have enough buttons for something like Elite Dangerous.

I'm using a Logitech F310 without vibration, but I'd really love to own a Steam Controller to play with. I was able to test that one at work and the feeling is totally different.

I have two F310 controllers and I managed to break one of them because I dropped it a few times on the ground.
It's not broken but LB and RB buttons are pushed in and I get no feedback when I press them but they work 99/100 times. It's a nice controller though but I need to buy a new one because it really bothers me and I want to reconfigure the controls and LB RB buttons are not reliable anymore so I try to avoid their usage :)
EDIT: if anyone can recommend me a controller, that would be very nice. I'm playing rocket league with it.

I bought an Xbox 360 controller last year for $15 (Might have been 2nd hand), but it works nicely. However I stopped using it now cause keyboard was easier to use >.>, some games still worked better on the controller though(so it wasn't a wasted buy.. I think).

Xbox 360 works well for me

Speedlink Xeox Pro Analog Gamepad
The controller has a xbox build and a switch at the back so you can swap between Xinput (Xbox) and dualshock (computer controller)

I forgot how to do the whole link text to url thing and can't find the discussion for it so here is the link

360

Xbox 360.

Usually a keyboard and mouse, except for games that work well with a controller. There I use a 360 (mainly on LEGO and racing games, but some others as well).

Logitech F710, seems good enough for me.

The Xbox One Elite is just totally in a league of its own. Considering I play more games with a controller than with a keyboard, it made a lot of sense to go high-end.

The Xbox One controller is an improvement over the 360 one and my current favorite - the microUSB connector is fragile, though. Now I returned and I'll get the new one (One S controller) when it's available. Bluetooth go!

Mousy and keyboard

Ummm, i was thinking to get steam controller (because of its integration with steam, maybe less compatibilty problems and future steam improvements etc..) but surprised to see 360 dominated poll so hard and now im confused :/

You might have added the Corsair Lapdog and the Razer Turret. The aim to be couch potatoe controlleresque mouse + keyboard combos. Generally your poll lacks an other option. Or atleast a 'generic BT' / 'some USB' gamepad.

Keyboard and mouse.
But for fighting games like MK and Street Fighter, I use Xbox 360 wireless.
Also use the Xbox Wheel for my racing games.

Keyboard (logitech ultrax flat) and mouse. As for a pad I have DS2 with a special converter to pc, it works good (in win7+ x360ce install needed) but somehow without vibration in games (in settings it is available). As for now pad I used almost exclusively for pes.

playstation 2 controller wasnt an option, but i vote that one.

I would never use anything but keyboard and mouse. Why ruin all the enjoyment? Why spread the inconvenience and horror I have to suffer with consoles?

Wireless 360 one, it's quite nice but the d-pad sucks, if the xbox one was a lot cheaper I'd upgrade to it but I'm not going to waste 60-70€ on it :D

my wireless xbox 360 killed my pc... like every time I plugged in the transmitter, my pc turned off...
So I got a xbox one controller now :D it's amazing
