It's funny, as a 20+ year macOS user, I've really struggled with file managers that are not Finder.
I don't think it's that Finder is brilliant -- it just encourages a unique set of power user workflows that aren't replicated elsewhere.
For example, Open/Save panels that act as drop targets, and navigate to the dropped file's parent folder. I use this all the time, and it drives me nuts when I can't do this on Linux (Nautilus) and Windows. Enter to rename, too. These habits are very hard to break!
You probably know this already but some don't (I certainly didn't for an embarrassingly long time): Rename is F2 in Windows and Linux (well, most distros File manager anyway).
