Yeah, I have a recommendation. Since you assert that "Speed is king", and the new host is 2-4x faster, who cares about the control panel and wiki? Google can help you with any stuff you'd use the wiki for.
Plus, considering the fact that you've already set up the domains, files, db, and scripts, I think you've got a pretty simple choice to make.
Check ya later! I'll be sticking with DH
