What are some other good note-taking apps besides ‘Obsidian’?

I know it’s suddenly become very popular but is it truly now the best?
Is their really no other note taking app that’s able to compete with it’s array of features?

There’s a few, even though that Obsidian probably has the best overall features.

Dendron. OneNote. EverNote. Logseq, this is probably the best one.

Are you looking for open source with biodirectional capabilities or does it matter?

it is depend with what you need.
for me, notion is enough.
