For me the complete package is actually FTX for trading. Binance is more a spot thing actually to buy something and take it off
I'm more spot in binance.
I've been hearing a lot of good things with FTX but I have never traded there. If some problems start to occur with binance, I might get on FTX if it's really needed.
But for now, I'm very well with Binance and I don't see myself changing anytime soon.
