I spent a lot of time in a… not-quite-legitimate version of PS 7 too. Feels almost like a rite of passage for many of us of a certain age.

And yeah, 7 was quite efficient and zippy, basically just 6 with a few new features and compatibility with newer OSes (first version to run natively on OS X for example). Ran it on a 400Mhz G3 without issue, which would be futile to even attempt with modern versions.
