I beta-tested the cat, so ran it for over a year on the G4, 450 MP and my mate's 1GHz 17" flat-panel iMac. That experience and reports from other beta-testers indicated every incremental build brought some speed increase in one area or another. I still run 10.4.11 on a daily basis and think stuff loads faster, Safari's snappier, etc. on Leopard. No other benchmarks, but I also beta-tested Panther and Tiger, so my experience is what I base my conclusion on.
