I did a clean installation.
I'm happy - things are quicker, Finder is much more responsive (and I can resize in Cover Flow without Cover Flow's previews changing size, finally!).
I also like the UI tweaks - the traffic lights are brighter but all colours richer because of the 2.2 gamma switch.
Okay, these things could be made noticeable in a 10.5.9 upgrade, but for $29 I ain't complaining at all.
