Now you have to keep track of multiple UIDs and can't easily share
things between them unless you make them all members of users and make
the primary group for all of them users, which is insecure.

And it makes a right mess!

Now you have multiple UIDs. Who owns common data? Or do you just
duplicate everything in Music, etc.?

Can't compare different distros or versions honestly since you're using
different desktops in each.

We've been around this block before. I think my method (while harder to
set up and perhaps a little daunting for someone who hasn't tried it
before) is causes less confusion, is *much* easier to maintain, and
enables data (where ever it is) to be owned by the same UID. You are
free to differ.
I somewhat resent your use of scare quotes around my name (which I've
had since I was 6 or so, back in the first half of the previous century)
