I know some people out there already made a thread about mouses, but is there any good wired mouses for FPS right now? I've only seen wireless mouses so far that tops it off
I recommend https://www.rocketjumpninja.com/mouse-search to get the basic idea about which mouse could fit you. Then try some local stores and look for similar mouses (or the ones you are targeting) before committing to one. Generally, you may find some of the suggestions not suited to the way you grip or move your mouse and it all should play a role when deciding which one to go for.
Do note that once you go wireless, you can never go back lol.
If you need any help with it, feel free to ask me, as I've tried out bunch of mouses in the last year (around 15).
