Having used other note taking software for the past decade (in particular outliners) Logseq is my new favourite, I just wish they'd focus on performance issues though.

Indexing and general responsiveness slows down massively once you have a few million words stored, and you have to break up your data into many smaller notes or you'll suffer even greater slowdown. Despite this I'm putting up with it at the moment because they seem to be making good progress improving the app and it's open-source unlike many of their competitors.
