Snow Leopard (10.6) also lacks batch file rename, automatic file versioning, full screen app support, trackpad gestures, and autosave. IMO that last one is huge—I remember losing many hours of work in Snow Leopard as a high school student, because whenever I got into the "zone" of writing I'd stop remembering to hit ⌘S.

Lion (10.7) has all of these features—Apple added a lot in that release. And while Lion itself was a buggy mess, Mountain Lion (10.8) and Mavericks (10.9) are basically just Lion with stability fixes.

I do prefer Snow Leopard aesthetically for it's higher contrast UI, but 10.7–10.9 are still well ahead of modern macOS in that respect, and there are even some individual visual elements I prefer in those versions, such as the Dock.

Mavericks is my favorite release overall. Launchpad is stupid, and probably the first place where Apple really began to break OS X's internal consistency, but it can be hidden away easily enough. Yosemite (10.10) is where things got really bad.

(Just for fun: Mavericks > Snow Leopard > Mountain Lion > High Sierra > Sierra > El Capitan > Mojave > Lion > Yosemite > Catalina)

autosave is awful when mandatory, as it is in FCPX. when optional, like Office, it’s great.
