Except for some exchange shit like Yobit and some new exchanges that may be cheating in the near future, most of the exchanges do not differ too much for me.
I am willing to use any exchange if they list coin or token that I want to buy or sell.
Also, in the last few years I've been using Kucoin, Livecoin, Cryptopia and Crex24 - trading at these 4 exchanges is quite comfortable for me.
