And ubuntu comes a bit bloated out of the box. At least for a "normal" power user that knows how to install the things he/she needs.
I'm also impressed from the support in the packages. For example, you need a new fancy editor? latest version? Atom, VS Code? sure, just install it from the package manager. Maybe need the latest of node.js? or vivaldi browser? It has them. It's much more complete than I thought. No need to look for .deb packages on anything.
And last, I won't have to change anything in 6-12 months when a new version comes out. There are no scheduled releases from what I understand. You can always be up to date.
Personally, I don't see any single reason to install ubuntu again.
