They’ve both been mentioned multiple times already, but I think you need to try out both Logseq and Obsidian and pick whichever you like better. They are both very similar, but take slightly different approaches. There are also plugins for each to make them behave more like the other.

I personally use Logseq because it’s open source and I like the daily journal and outlining features. I used and enjoy obsidian, too, and it has plugins to improve journals and outlining.
