Syncthing vs Obsidian Remotely Save

I want to sync my Obsidian files between Windows and Android. Between using Syncthing and Obsidian Remotely Save plugin, which would be an better option for me if I only care about sync performance, security, regex support and battery usage?

Syncthing seems to be a better option, though I'm not sure whether it supports encryption when transmitting data and regex. but it requires constant running in the background so I would say it consumes more battery power than remotely save

Remotely Save plugin is a bit buggy in my opinion (experienced a few file lost and incorrect sync when creating new files) but it supports encryption in transmitting data and regex.

thanks a lot in advance
