Well…trying to remember. I read about them all and I think at the time I felt Umbrel had the nicest interface and best built out App Store with a good variety. I think the others may have been missing some stuff. I know others have opted for or moved to Start 9 for better configurability (not necessarily something I need), but I’ve also seen some complaints about it not having some apps. Best thing to do is read reviews about all of them and see what best fits your needs.
