We use Universal Type Server at work and I use Suitcase Fusion at home. I had another one and I can't for the life of me remember the name but it was actually pretty cool as it sorted fonts visually rather than by family. I am sure I have the original download somewhere in storage at home... have to look that one up.
Thank goodness for personal cloud storage and being able to get me files from anywhere.
It's as much a creative tool as it is a font manager. And you can use it along side any other font manager so it's not an either-or.
