I feel coinbase because Binance has a fee of 30% if you wanna sell your crypto. So yeah I think coinbase is the best exchanger for me. Theres different opinions as everyone likes different exchanges.
Personally, I believe that Coinbase is very good as well. Although, I didn't like what they did to my friend recently. They put his fund on hold for 2 days for one silly excuse. I have never had that experience with using Binance.
