After reading the README, the only missing thing seems to be the equivalent of Dataview from Obsidian. Will wait for something like it before considering switching.

Is vscode the new electron?
I tried switching to this a few years ago, but switched back to Obsidian. My problem was actually the strongest feature: the VS Code integration. Only about a third of my note taking is related to software development, so for me going into VS Code the other 2/3rd of the time was clunky. If 100% (or close to it) of your note taking is software related, this is a great product.
