But, I heard that FTX offer lower fees. Is it right?
Right and mandatory KYC right now.
Both exchange are best but I prefer binance exchange is best binance have full security system and also low trading fee so too much people like this we can put or exit any order within seconds on binance FTx is also best but now some feature not good in FTx
Binance is the best exchange because Binance is an old exchange, so they have a robust security system and low trading fees, while Ftx is a fairly new exchange, but I'm sure in the future Ftx will overtake Binance.
Wrong, FTX offer lower fees compared to Binance. It looks doesn't that much, but if you're a trader such difference is worth to gain more profit.

In terms of security, binance is secure.

Hacked Exchanges since 2011 and search "Binance" you'll find they ever got hacked before. It doesn't mean FTX is very secure since there's no hacked history, but it will happen once in the future. That's the risk of CEX.
