I don't know them directly but let's wait to see if someone else do.
One of the big differences in hosting is the service. You can call them and ask a few technical questions to see if you feel comfortable. Look for the answering time, the disposition of the person to answer your questions or to redirect you to someone who can. Salespeople can be very persuasive, so write the things you want to know before you call.
If you are planning to use a programming language (ASP, PHP, Coldfusion) see if they support it.
I hope this helps
