New mouse

I have the Deathadder and used Vengeance for some time.
They have huge differences. Deathadder is really light and it is quite big (in case you have huge hands).
On the other hand Vengeance is really heavy because of it's metal base and quite short, but it is hella comfortable.
I don't have the slightest clue about the Logitech one.
So in the end you have to choose what fits better to you :)

I have used Deathadder for a long time, but now prefer Logitech G9X over it. For my next mouse, I am also considering the other two options you mentioned, as well as Logitech G700.

How about hamster ?

Tt Esports 10M. Sexy, keeps you cool.

Go for the new Logitech G303 is a perfect mouse... i got this.

My favs: MX510, MX518, G400

I just bought my G502 this week and its pretty good so far, one of the best sensors out there and really good fit. I have more of a fingertip grip but I can feel my palm touch the mouse at times so it could be the mouse made for me or i just switch between the two grips.

Stay away from the DeathAdder models. While they are really good mice, they are prone to double clicking. My Chroma is 4-5 months old & double clicks like a bitch.

I use a G502, Deathadder and Deathadder Chroma. They are all great, but I would have to pick the G502 over the Deathadders.

Logitech G502 Proteus Core ftw

It looks like the G502 is most popular so far, will look more into that, thanks for the advice, but keep them opinions coming please

How about the sensei Wireless or the steelseries rival? =)

The Logitech will probably be the most similar in shape to what you're used to, and although I've never used a Razor, myself, I've read numerous complaints that their build quality isn't great and that they break easily, so that's something to consider.

I was a Logitech fan for the longest time, spanning a g500 and 2 G9x over the course of 15 some-odd years. About 6months ago the 2nd g9x starting getting a bit wonky on me(known issues), so I started looking for a new one. I wasn't really impressed with the new designs by Logitech, and after weeks of pressure from a friend I decided to heed his advice and try something completely new.

He had been using the SteelSeries Sensei for a couple years and currently had 3 that he was consistently using(work,laptop,desktop). I found a good deal on one and decided to go for it, and I honestly couldn't be any happier. I'm a pretty die-hard Logi fan but the SteelSeries Sensei is a great choice.

Edit* That said, I do really miss the G9x but look at those prices :(

I'm very happy with my CM Storm Xornet.
