I have had no issues with Leopard's stability at all (watch, I'll go home and everything will have crashed).
Spaces, which I didn't think I'd find useful at all, since I've got a 30" and a 23" Cinema Display, is a big hit. There are a bunch of programs that I routinely run but don't need to observe (Handbrake, for instance). Setting them up in their own Space is perfect.
Of course, I love Quicklook, when I remember to use it, and Stacks are great. I didn't mind the lack of a hierarchical folder view, but I am glad that Apple listened and added it as an option. The new look to the Dock and the translucent Menu Bar are nice - and I often feel that I was the only one who liked them.
Of course, I rejoice at the Spotlight That Finally Works, but the best, very best thing about Leopard is Screen Sharing. I keep a PowerBook in my bedroom, three floors above my office (and my Mac Pro) and rather than struggle with good ol' Chicken of the VNC, I can access my Mac Pro without a second thought. I admit, I've not yet tried Back to My Mac, or sharing through iChat, since I no longer travel with my iBook - my iPhone is more than sufficient. I should go with the PowerBook and try it just once.
There are a number of annoyances with Leopard, though. The new system folders are ugly and boring. Mounted disc images often linger in a Finder window sidebar long after they've been ejected. Entering new appointments in iCal sucks, too. But these are truly minor annoyances - particularly since I have to spend a large part of my day suffering on Dell.
All in all, for me - Leopard is fantastic. There are so many new features that I have yet to implement in my workflow that I've actually bought David Pogue's new book (I highly recommend it).
