I tried Obsidian but ultimately landed on Logseq. The short version is that the workflow with Logseq is very block-focused rather than page focused. Your organization can be more organic; following tags and links rather page/hierarchy. Finally, Logseq wasn't getting in the way of me using it for work. Obsidian's license model made my situation... murky.

That said they are not mutually exclusive. Plants if folks use both. Obsidian's experience is much better for deeper subjects focusing on a specific page. Logseq is much more block focused.

Logseq is also not without it's flaws. The app can be super slow in large graphs, and they are rewriting the backend so feature development is at a near standstill right now. No collaboration features and a shakey business model makes it hard for me to recommend hard.

TL;DR: Logseq is more capture and block focused. It's worth checking out but hard to recommend for everyone.
