I was like batch 5 of the AMD framework 13 running Arch and Gnome on it.
I did have some problems with suspend/nvme drive that was fixed by replacing the nvme. If you go with their drive you’ll probably be fine (I just grabbed one I had laying around). Ever since then the laptop is perfect. If you do get it check out the Archwiki article that has a lot of helpful tips for tuning your OS to the Hardware
I feel that. I’ve used Linux before systemd but when I went into the “nitty gritty” by using arch systemd had just been implemented and everything I learned about startup services init etc. was systemd based. When I started my career working in servers they were redhat/CentOS so still systemd and when I switched jobs Debian already had made the switch so (most of) the systems at my new job were also systemd based. Of course I learned the basics of init files and even some rc.d but systemd still makes the most sense to me and like you say it’s “comfy”.
