Hitbtc
I only recognized 3 from the list which are Cryptopia, Hitbtc and Yobit, I use to trade on cryptopia, but I stopped use it when they started to have issues, So I would go for Hitbtc since I didn't face problem with them yet, for Yobit is shit exchange.
I also prefer HIT BTC, I've have encountered serious problems from my account in yobit like someone is trying to hack my account also same in cryptopia. But in HITBTC they have authenticators to choose from strict security for your accounts.
