I use it multiple times a day, and it's great! It doesn't try to hide details from you, but it does put a well-thought out GUI in front so you don't have to stumble around. It's not perfect, does take some getting used to, but it's stable and relatively comprehensive. I love it. Caveat: I'm mainly using it for home usage in my home lab.

I also love that I can drop to the CLI easily for scripts and it plays perfectly well with virt-manager, and it can be used easily over SSH to manage VMs on a remote host (which is key to my use case).
