I have yet to try PS7, but I always find myself using PSP 7 rahter than PS6 for graphics work. Mostly because PS is "overkill" for the relatively simple stuff I work with. And although I do have PSP 8, I hardly ever use it for the same reasons I don't use PS. It's just too bloated with functions that I never need. And since PSP 7 is compatible with my favourite .8bf plugins anyway, it all becomes a no-brainer.
