So far pretty damn happy with the server. It's only been a day, but I've really pushed it. I'm running the 3 gig plan. Even though there's only two of us, I might actually have to bump that one up to the $10 plan. The reason being that I've unlocked the view distance on the server from 10 to 32, which is massive, but necessary for my playstyle. No compromises!
The difference, I'm finding, is the customer service. It's not that anyone has been rude or anything yet, but the response time is glacial (understandable being that it was over the weekend, so no big deal) and the one guy I did talk to couldn't spell very well and didn't have the right information. Again, total pass because I was asking stuff that was very customized for my unique specifications, and their mistake was only trying to save me money (they recommended a lower tier that wouldn't even run this thing). My only advice would be to make sure you already know what you're doing before jumping in.
It was a bit laggy at first, but seemed to stable off by the end of the day. I think I had the same thing with mcpro. Can't hate this price. I'm overall pretty dang happy. The customer support for MCProHosting is really, really good, but it's not "let's pay three times as much" good. This is the way to go.
