My mouse recently broke and it was a cheap £15 gaming mouse as I didn't have a big budget for such things at the time of buying. However I can now afford a higher quality mouse and I have done some research only to find that it's more or less down to preference. The two I am looking at currently are the Razer Mamba Tournament Edition or the ASUS ROG Gladius II. Can someone tell me which of these is best or suggest another mouse that would be good. (I mainly play shooters more specifically Rainbow Six Siege and PlayerUnknown's Battlegrounds so keep that in mind when suggesting other mice or telling which of the two I said is best). Thank you for any suggestions.
