I'm not a gamer, but getting a high quality mouse often means getting a gaming mouse, so here is my brief opinion.
Razer mice are known to be excellent, however, since the introduction of Synapse (a mandatory program which stores your mouse information on their server) I would not recommend buying anything from them anymore.
Steelseries is another popular brand. Something like the
Sensei is very highly recommended among many gamers.
Also, Logitech is known to produce good I/O hardware, and this includes popular gaming mice like the
G9X.
But before you settle on a mouse there are a few things you need to determine.
- What type of games do you play? This often determines what type of functions you need: do you need super-high DPI/CPI, or do you want a lot of programmable buttons? Do you want high performance (wired) or mobility (wireless)?
- How do you grip your mouse: full palm, just your fingertips, etc.
- Do you have large hands? Would you like a small mouse?
- How much are you willing to spend on a mouse?
- And finally, you need to actually put your hands on a few different mice. The feeling of a mouse is highly subjective, but also the most important consideration.
That's my two cents.
