GNOME looks like macOS as KDE looks like Windows
I'm not using a macOS theme, but all of the buttons are in the same places and it works great with my macOS muscle memory. Same thing with key shortcuts, KDE has a customizable shortcut system for practically anything you'd want to do.
I tried doing the same in GNOME and it seems that they want you doing things the GNOME way, which is just different enough to be an annoying experience, personally.
Where macOS has always been about progressive disclosure with tons of little power user affordances hidden in plain sight, GNOME is more about paring everything down to the bare essentials in a polished way.
While it's been a couple years since I last used a Mac and I thankfully haven't had to use Windows 11 (only 10, sparsely), I've used all four platforms within the past 3/4-ish years and I'd say it's a pretty accurate blanket statement.
KDE is really intuitive to use as a previous windows-user, and gnome... well certainly feels like they're _trying_ to be MacOS, not sure how familiar it'd actually feel to a recent MacOS convert though.
The similarity is more vague with GNOME (3) and Mac OS, IMO.
