I never used conbase and zb but I often do trade on binance and according to my estimate binance is capable enough to dominate the crypto industry for a long time if the exchange keeps continue its current momentum of progress which looks not a big deal for this exchange.
Each exchange has its drawbacks, you will not find a single digital marketplace with an impeccable reputation. It is necessary to be guided not only by the size of commissions, pay attention to the convenience and quality of the platform - technical support works quickly, whether it solves your questions qualitatively.
