The journal is the biggest reason I move from Obsidian to using Logseq regularly. There is so much less friction just going to journal and writing ideas rather then figuring out where to add the note too before typing.
I haven't used Logseq, but I've found trying to categorise notes in Obsidian made me use it less so I just rely on backlinks as tags and to create connections between notes and dump most things in the primary vault folder. I've gotten comfortable journaling using daily notes with templates.
That's why I prefer Logseq. I never think about what folder something fits into. I write in the journal and tag stuff. Once there is enough information regarding a topic, I create a page for it. Also, the fact that Logseq is open source is a major plus in my eyes.
