Which is the Best Crypto Exchange Markets

Comment below the Best Crypto Exchange markets and what you currently use?

My First Exchange was Poloniex, it was simple to use but after a while I did not like some of the options they had and the site was down quite a bit in the past.
Then I found Bittrex and it seem quite interesting with new coins and its speed.
Then I found Yobit and the "Invest" options they have. But not sure about having large amounts there.
Now just found out about Binance looks promising like the early options to invest in IPO's
