I haven't used obsidian, but have been using Logseq [1] (which a lot of people have mentioned to be similar) for over a year now and super happy with it.
The data is stored locally as md files, can be versioned using git which is a big plus for me. Also the workflowy-inspired zoomable bullet list is great to have for large outlines.
With the built in support for tags, image pasting, tasks, journaling, templates and static site publishing it just ticked every box I had out of the box, and I am yet to even start exploring its rich plugin ecosystem.

Oh, and its completely open source.
