Which crypto exchange do you use? Why?

I have been in crypto-currency since a long time, till now I have used c-cex, poloniex, binance exchanges.
I left trading on c-cex as it made a bad impression of itself when they went for 1 month holiday with no contacts and no responses to queries. I got my currencies blocked there for a month and it did worry me a lot.
But, when i got a chance to withdrew from there, i took everything to poloniex. I have been using poloniex since a long time but never totally focused on this one before that incident.
I recently came to know about the binance exchange which has made a great positive impact not only on me but also on my friends. Its CEO has been registered as the crypto billionaire by Forbes.
Which exchange according to you is the best one and why? Any good or bad experiences you had?
