Nice write up. Hope we both will be fine with our installations =)
Regarding “new user” - that’s true, e.g. average person has much steeper learning curve than software dev, DIY enthusiast playing with Arduino or gamer who has his own server for favorite game in the cloud and etc. They might be all “new” to Linux as desktop OS, but not on the same start line.
Though looking at EndeavourOS and recalling my experience with Mint and Ubuntu, it might be possible to have windows like (when it comes to easy to use) installation\configuration and experience out of the box.
Very good review actually,was looking for something like that souole of hours ago and couldn’t find.
