I honestly tried to love obsidian because of how easy it is to set up and how user friendly the UI is (plus there are tutorials and tons of articles), but I just can't get over it being offline and only means to sync are looking for a plugin that will use git/dropbox etc plus there are no mobile app anyways.
Right now I found that notion is perfect for me. It does not have a mind mapping functionality but its very good, super easy to use (to the point it being intuitive) in all other areas AND I have perfect sync, mobile app and web app so I can use it on my work laptop, phone and personal PC without any problems
Honestly, it's worth paying for Obsidian sync. Sure, you can try and do some git/dropbox style combo, but Obsidian Sync is proper magical along with the mobile app.

But if you don't need that, obsidian is amazing
