I’ve had Fedora on several computers, and everything worked for quite a while while. Eventually though, things just began to break randomly - probably a sign of me not doing much maintenance.
The most common issue was Gnome Software center failing to update anything. I just ignored that app, and continued to upgrade through the CLI for a while. Eventually, I just got tired of that, and installed Debian on my HTPC.
Now I can finally treat that computer the way I want. Just install, watch videos, update when needed, and ignore the rest. I have another computer for satisfying my tinkering desires, so this one is just for the videos and very light browsing, but not much else. Therefore, Debian is the perfect distro for this kind of use.
Also, the HRV graph is something that watch can’t provide. Some other watches do measure HRV, but you only get a daily average, so you can’t really draw any conclusions about the shape of the graph.
