Well, you can be sure that no private server will offer you the same server stability of joymax's server; joymax's team contains 5000 team workers who are working together to maintain smooth servers, while the private servers are just random people (may be 2 or 3) even if they are a hundred, their work will not surpass the work of a 5000 team worker for sure.
Anyways, this thread will be spammed and off-topic-ed if i left it opened so, it is closed.
