I've heard good things, issues would mainly pertain to somehow walking non-technical family members through setup.

As well given I don't have a security background I try to keep my self hosted stuff to non-critical items. Plex going down matters less than "I can't login to my bank account because the optiplex decided to die while I'm in the office".

Albeit knowing how locked in many users are made it a great target for PE so should've seen that coming.
