I have Had I think Every Provider in the GameServer Hosting Industry (well the "Big" Ones anyway. Clanservers,Velocity, Hi-Def,a2g, etc.....), I Would say is the Best GSP Out There. My Reasons Would be :
1. Active and Friendly Support Staff ( On About All the Time)
2. User Friendly Control Panel
3. They Actually Help You Out
4. They Dont Hide Anything or Ignore You.
5. Prompt, Quick, and Reliable Staff
6. Good Pings
7. Good Performance
8. Best Registry
Well Thats What NFO Has Been With My Experience with them.
