I like Binance and Bitfinex for different reasons, it depends what the purpose is.
You can open an account on Binance for free or request more information here: https://www.binance.com/?ref=35004361
I have used Bittrex for almost all of my transactions for quite a while now. I use Coinbase to buy crypto using a debit card and then transfer to Bittrex when I need to. I have a Ledger Nano wallet that I store almost everything on that I am holding right now. I have used Binance before but it isn't my favorite. I may go back and take a look now that they are offering transactions via debit card though! That is quite game changing and I am hoping that it works out for Binance!

Binance because the fees/exchange rates are a lot lesser than other crypto exchanges.
There are many exchanges out there that are really doing fine. However, my best exchange remains @blocktrades and then I can talk about Luno and others
I see a lot of people say Binance, I only like it for the volume and number of listed coins. The site alone is very slow and buggy in my opinion, but they are alright I guess. I like Bittrex the most.
I really like using Binance and Kraken. They have both been really easy to use and the KYC process though time consuming is fairly easy. I would say if you are just getting started though you might want to look at Coinbase. Especially if you are in the US. It is a quick easy way to get started in crypto and from there you also get access to a GDAX/Coinbase Plus account.
For me it is Binance. The exchange fee is really competitive than other existing major exchanges and I like the interface, its smooth and fast too. I think almost all love Binance over the the others. In a short period of time Binance gained a lot of popularity and it is because of the low & competitive exchange fees. That is why I love Binance.
Binance is the best, due to their high commitment to customer service.
I use Binance, Bittrex for altcoin trading. For margin trading, I use Deribit: Fast, reliable and simple.
