I don't have a lot of experience with Minecraft hosting services, and I haven't had any reason to interact with customer service so far, so it's difficult to evaluate ScalaCube in detail. However, I can say that setting up my Minecraft server was a pleasantly easy task. I'm versed in Linux, and so I was also pleased and impressed with how easy it was to manage my server without assistance. I've had my server for a number of months, and was able to accomplish everything I wanted to with a minimum of fuss. I don't give ScalaCube a top rating only because I probably have not been using it long enough to experience all the possible issues that might arise with any hosting service.
