Which mouse it the best for CS:GO and other fps Logitech or Steelseries

So i have a really shitty mouse and am looking for a new one and i have enough money for Steelseries Rival or Logiteh Fury Hyperion my prefered grip is claw if you have one or both of these mouse please give me your opinion on them i would really like to know :D

Buy both and try them out, then return one. Everyone has a different preference in mice and in competitive gameplay, you can just take someone's word that it's a good mouse. Frankieonpcin1080p has a good video on choosing a mouse.

I use the Steelseries rival and like it.
It's a fairly long mouse which works for me as i have big hands. I would love to buy a mouse that would make me better but I think i am limiting factor when it comes to my K:D ratio, not the mouse :-)

I would suggest Steelseries but everyone has a preference

The Rival was made with by SteelSeries with Counter-Strike in mind (my brother is their global marketing manager...) and it feels fantastic.

I personally prefer the Sensei mouse because I like a smaller mouse for gaming but still use the Rival at my office PC and it works great.

I use a Razer MMO house. Sounds weird but it's nice having a MMO mouse because you can quickly change weapons using your thumb.
