Easiest question ever.
Hands down it would be techiemedia.net
Reasoning: Great service at a great price. Have been EXTREMELY helpful to me in more ways than words can justify. Always reachable. Super fast tech support resolution times. Never plays the nickle and dime you to death game. Fair and very honest staff. Owners have been in this business a very long time and are here for the long haul. They never skimp on quality of bandwidth, the pipe, nor the hardware. I could go on and on.
A large number of sites use them and use them for a damn good reason. They are actually so good at what they do they have no real need to advertise, they do not buy sigs and if you see a sig it is just there as a thanks. Unlike many hosts they get more than enough clients via word of mouth after they have had deals go south with other providers.
So once again
