Nextcloud vs Syncthing for PKM notes?

Cross-post from: https://lemmy.world/post/9282945

I'd like to sync my markdown notes between devices (laptop and phone), which service is better: Nextcloud or Syncthing? Any other important idea I should know?, like latency times, or maximum number of synced devices, what if I edit the same note from both places without internet and then both get connected to a network... For example, I know Nextcloud let me have a history of the notes.
