I upgraded from Tiger to Leopard (well, technically I did a fresh install, not an upgrade), and saw a marked performance increase as well. The Cover Flow and Stacks user interface features have enhanced my workflow by making it easier to access my files. Spotlight searching seems quicker and better indexed. I also love the To-Do, Notes, and RSS features of the new Apple Mail. Bottom line: I love Leopard.

Are you using an Intel or PPC-based Mac, Joseph? I'm on an Intel Core 2 Duo MacBook. Not sure what the performance is like on an older PPC system, though they are supported.
