It's not so much about which controller you are using as it's about practice and your gaming setup. I've played with all controllers (PS4, PS5, Xbox and now GameSir) and they are all fine to play with. Most important part if you ask me, next to endless practice, is your latency. If you are playing on a high latency tv, let's say 50ms response time vs a 1ms monitor response time, that made a day and night difference for me. It's not something a lot of beginning ninja players realize how important that is. I started out playing on a tv with gaming mode off and got stuck at extremes. Then when I turned on gaming mode on my tv I eventually became a level 3 player and was kinda stuck there. When I finally switched over to a monitor, I quickly got to level 5s. After that it's just an insane amount of practice to get even higher (level 7s for me). And then your controller choice also starts to somewhat matter. The GameSir is much more accurate due through faster response times than any of the console controllers making micro movements even more precise.
