EndeavourOS is basically Arch with a nice installer and a few extra QoL packages while Manjaro manages their own repositories and adds things like mhwd that change system management to be a little different than Arch.
I much prefer Endeavour since I already do everything from the command line anyway. Also, while most info about Arch applies to Manjaro it doesn’t always and I found that very annoying when trying to troubleshoot.
I’ve also installed Arch a few times and it went fine, but the Endeavour installer is a much nicer experience.
That was my thought. Most games that are on both PC and Switch are not big enough to want to pay Denuvo for their services. Any game that is big enough to care probably also can’t afford to take the Denuvo performance hit (that they claim doesn’t exist) on the under-powered Switch.
