@noboilerplate The database version has been stuck in perpetual development hell for a few years now. I'm not overly concerned about it personally, since it already has markdown export. Plus, it uses a SQLite DB for the back end, so worst comes to worst I would be able to explore the data and write my own conversion software.
The plugin ecosystem is definitely less mature, but I also have not desired more than a handful of plugins to make it work for me. I only have 12 plugins installed currently, most of which are just for UI tweaks or small "shortcut" tools. The only plugins I've needed that truly alter Logseq's behavior are for KOReader annotations import, mermaid diagrams, and displaying furigana.
I'm not trying to argue that Logseq is better than Obsidian on all fronts; I just find that, for me, it's pretty much perfect straight out of the box. My brain already operates best in bulleted lists, so that format also being great for Zettelkasten is just a win-win for me.
