WHAT ALTCOIN EXCHANGE IS BEST TO USE?

[hangar18]

I choose Poloniex and Bittrex have a good service I think,
If I have problem they can solve quickly

I have been using around 5 to 6 altcoin exchanges.
My favorites are BitTrex, Cryptsy and HitBTC - in that order.

I have also used AllCrypt, Poloniex and a couple others, but my choice stays as stated above.
