Obsidian is great for solo use, but then so is Apple Notes and a dozen similar options. Where Notion shines is team based sharing and collaboration. There's really nothing else like it with the same feature set.
Once iOS 26 drops Apple Notes will be much-much more useful with the combination of supported linking between notes and supporting Markdown.
Before it rapidly became untenable as a place to actually store my notes. I use it more as a "temporary note" that will be moved to the proper place later.
