Among the both of them Binance is the best exchange there is. Binance sits on top of the list when it comes to best exchanges for anyone that wants to be a trader. That's the choice for the majority but that doesn't mean that everyone is going to make it their choice.

There are people who might prefer a different exchange due to something else that the offer that isn't available on Binance. There are lots of other exchanges that are also on the top list, Bitmax is not even on the top list and it is not even a popular exchange , that's one thing I know for sure. There are other exchanges like Bittrex, Bitfinex and even Coinbase.

Coinbase is another exchange that is very popular. I think its level of popularity is the same as Binance but a lot of people avoids Coinbase because their exchange is one that is being regulated (people here don't like making use of regulated exchanges. Newbies always choose Coinbase because it is very easy to use and they offer good services, though not available to all locations, and their platform is secured. But don't trust an online platform because anything can happen.
