Maybe one negative experience here:

I’ve used self hosted livesync for months before migrating to actual Obsidian Sync.

Reason being my vaults kept getting off sync and I had to keep rebuilding. Not to mention that moving files between always ended up being super tricky and would work half of the time. I tried really hard to like it but it just didn’t stick.

The plugin sync was also horrible.

I wonder if you’ve also had any issues?
