I am by NO means an expert at AOC. Highest rate was 1890 or something 5 years ago. In FPS games that I mostly play now, I LOVE the Logitech G400s. It's replacement the G402 I have never tried, but I've seen the buttons placed a little funny but it's supposed to be an even better sensor and more features of course. I love the G400s so much I bought 4 of them for backup. It's all about the FIT in hand, and to me there's none other that fits me like that one does. I've had the Deathadder (which only had perfect side buttons in my opinion) and I've had the ROCCAT Kone and other logitechs as well. I sold my original Deathadder and 2014 one and the ROCCAT Kone XTD on Amazon, got rid of all previous mice. G400s, not many features, but for me, it's all about the fit and feel, and that one gives me the pinpoint precision control for FPS. It's perfection.
