I think if you can Binance will always be the best, however aside from that there are small ones you can always talk to, if you go small enough you can talk with the owners of many exchanges. Right now I personally know owners of 6 exchanges, 4 local and 2 global and I have talked with them for a coin I personally worked for and I can tell you the best one right now is IDAX, they are doing their best and they are super small so you would both be getting in easily since they are small they need coins plus they are fairly easy to reach.

But, if you want to go for the big ones Kucoin is one of the best and I have seen their security which is awesome, they are really caring about the security part and it would be very difficult to hack them as well. So from small (idax) to middle (kucoin) to big (binance) it all depends on how big your own coin is.
