In Obsidian , you can even sync to github or dropbox with community plugins . so price wise it is free
Also Obsidian has much better search (using community plugin) which is lacking in noteshub
+1 on the third party search. Quick Switcher plugin lets you bring up a hotkeyed modal to search across all note titles/headings/subheadings/tags all in a single fast search interface.
I wrote a plugin called Relay that makes obsidian multiplayer with live collaboration (using CRDTs), and there are a few others in the space too.
Obsidian sync is also great for e2e encrypted sync for your own devices if you don't want to rely on third parties like GitHub.
