First of all, thank you @HydraGaming for all the effort you put into your reply. I get so impressed by this community sometimes.
After going through your recommendations and all my options, I've found that it seems for my hand size and game choice, I am stuck between 2 mice.
Roccat Kone Pure Military
Logitech G303
Now that I am down to these two, what do you think I should look at to make my final decision? Since I'm very unfamiliar with Roccat mice, the only things I know is that the Logitech mouse has the best sensor on the market, the Roccat doesn't, and the Roccat technically has one more button that I'll probably never use. In case it helps, I answered the 5 questions from the first video.
Hand size: 17 and 9 Grip: Claw Games: Mostly MOBA and some FPSs Competitive: Like to win, but not "professional" Budget: 40-55
Thanks!
EDIT: P.S. How to snippet. I can no forum.
