I rent a server from CH, and things seem to be running ok. That being said, I utterly hate it. I've had multiple problems, even to the point of not being able to access my server for a month or two at a time, getting to the control panel can be a pain, although that might just be my ISP. When I do get to the control panel however, using it is a joke. I can't get to all the mod's configs from their interface, the only way I can is to use Filezilla and go through each mod folder. I can't even download their desktop clients, because one link 404's, and the other kicks me to my router (again, that might be my ISP). The customer service is slightly better now than it was when I first started renting, but not really. I used to get daily emails telling me that the server went through an nightly autosave, and to click for the report, but there was no place to click. The backups didn't exist.
If there was something else, I'd swap to them in a heartbeat, but there isn't much else.
