So much depends on what you want from the panel.
We were with RunCloud (well, still are) and moved our core to Enhance. Here is a little table I made - https://rve.sikmo.cz/. We discussed it even on a call with Raj (RunCloud CMO) and few members of their team.
But our goal is to build custom frontend panel (already working) and sell hosting / vps plans. But RunCloud as-is and now with workspace is really great.
Important note: we are / always were on yearly Business ($37.5and now $41 per month). So bear that in mind.
