It's pretty simple the exchanges should make the whole process of trading, P2P more easier and user friendly and they just need to competitor benchmarking with Binance to see where they lag if they really do or not because most of the users just got used to Binance and it's taking them sometimes to adopt to other exchange hence ethey are cribbing about i even if there is absolutely no problem with the exchange and it's interfaces.
I have a similar feeling as well, most people have been too dependent on binance to explore others exchanges perhaps the little challenges they face navigating the respective exchanges UI....After trying out a few exchanges, I realized Bitget has one of the best UI and their P2P is pretty good. I even got some BGB on my first P2P transaction
