KDE NEON(20.04) vs Ubuntu Mate (20.04)

I just wonder: Why would you do this?

If it’s the only computer you have, fine, I understand. Otherwise? I’ve seen a Pi4 running KDE-Neon smoothly, but it only uses a small fraction of the energy an older laptop or desktop needs, so I guess, it’s a better option.

BTW: My laptop is 12 years old (but with SSD) and it runs totally smooth.

As far as I know, the current OS X theme is pretty much a copy of the DeepinOS desktop, but I’m not entirely sure as I don’t use either of them.
