It's actually not too bad to run, it's just that my community instance has grown a lot, and is close to four years old at this point. Issues crop up, I mostly wrote this guide to share some insights on how I deal with things.
Peertube is essentially mastodon or lemmy with videos. Its trivial to set up compared to the other two. I run a private instance so I cant talk about the rate of issues but from an experienced admin perspective, its no more of a problem to set up and run than the others.
But I too think that long term it would be great to have more user friendly setups as to enable less experienced folks to host it.
Honestly, self-hosting is kind of the way to go, so long as you stay on top of your backups and storage. There are a lot of Object Storage providers out there that offer reliable storage for cheap, it's a good investment if you plan on uploading somewhat frequently.
