Bybit and Binance still remains the best for mid range satisfaction, although both also have their bad side and as mentioned by others, what really matters to us trader is to get used to the exchange app functionality to some level, and keeping up with whatever updates, since if comparison is set, we really will not have any exchange Mobile apps that will definitely meet up with our 100% desire.
For best functionality using a PC fit my trading mode most and for over a year now I haven't use Mobil device for trading, I am most used to trading with PC right now.
