What wild customisations are you talking about?

As someone who used Linux (Ubuntu, Fedora, OpenSuse, Arch) exclusively from 2010 and recently moved to bazzite, I only see positives from the switch.

Most of my usecases work OOTB, and for everything else I use a container workflow. I like that there are fewer ways to mess up upgrades. I like that flatpaks are well integrated.
