A lot of people are going to recommend you mint, I honestly think mint is an outdated suggestion for beginners, I think immutability is extremely important for someone who is just starting out, as well as starting on KDE since it’s by far the most developed DE that isn’t gnome and their… design decisions are unfortunate for people coming from windows.

I don’t think we should be recommending mint to beginners anymore, if mint makes an immutable, up to date KDE distro, that’ll change, but until then, I think bazzite is objectively a better starting place for beginners.

The mere fact that bazzite and other immutables generate a new system for you on update and let you switch between and rollback automatically is enough for me to say it’s better, but it also has more up to date software, and tons of guides (fedora is one of the most popular distros, and bazzite is essentially identical except with some QoL upgrades).

How common is the story of “I was new to linux and completely broke it”? that’s not a good user experience for someone who’s just starting, it’s intimidating, scary, and I just don’t think it’s the best in the modern era. There’s something to be said about learning from these mistakes, but bazzite essentially makes these mistakes impossible.

Furthermore because of the way bazzite works, package management is completely graphical and requires essentially no intervention on the users part, flathub and immutability pair excellently for this reason.

Cinnamon (the default mint environment) doesn’t and won’t support HDR, the security/performance improvements from wayland, mixed refresh rate displays, mixed DPI displays, fractional scaling, and many other things for a very very long time if at all. I don’t understand the usecase for cinnamon tbh, xfce is great if you need performance but don’t want to make major sacrifices, lxqt is great if you need A LOT of performance, cinnamon isn’t particularly performant and just a strictly worse version of kde in my eyes from the perspective of a beginner, anyway.

I have 15 years of linux experience and am willing to infinitely troubleshoot if you add me on matrix.

Stop worrying about the country of origin. It's a FOSS project. The vast majority of Pop's components are developed independently of the company, and by citizens of various nations. Applying the "USA bad, so product bad" rhetoric is a seriously shortsighted approach. Consider instead the amount of influence exerted by the company. Does Ubuntu still seem like the better choice just because the company is headquartered in the UK?

Besides, if you really want to cut American software out of your life, start with Linux and GNU. Torvalds was born in Finland, but he is a naturalized US citizen, and Linux is developed on American infrastructure and includes significant amount of work from American developers.

Debian is a community distro. Ubuntu is downstream of it.

Yes, at least Lenovo Linux laptops are 140$ cheaper.

Take a look at Framework, or System76 for Linux first hardware.
