RunCloud does many things poorly (like disaster recovery) and their magic caching plugin has issues. With Enhance you're in control and can get MUCH better performance for much less (if you know how to optimize and don't expect a magic "optimize website" button).
Enhance has many UI bugs and clearly not enough developers. I wouldn't use Enhance if I was selling mass hosting but its perfect for hosting the sites I build and manage.
I would have said a year ago: "in about a year Enhance will be production ready" but they released a buggy v12 instead of fixing v11 bugs and now they have more v11 AND v12 bugs. You still can't trust backups/restore/disaster recovery.
