The main response you will get is that if you want good performance to a pool, then pick one in China, anything going outside the Great Firewall of China or Golden Shield is going to suffer performance degradation or even blocking.

You could set a secondary pool in such as Antpool or f2pool and capture the hashing power lost to the main pool there.
