Bear 2 vs Obsidian
Bear stands out as a more polished, aesthetically pleasing product with a simpler set of features. Unlike Obsidian, it is an Apple-exclusive app. The long-awaited Bear 2 update brought a lot of new features including backlinks, tables, footnotes, Markdown hiding, nested styles, folding, table of contents, custom fonts, and more.
Obsidian is a lot more sophisticated in its note-linking abilities. You can easily build and navigate whole knowledge bases with Obsidian. That said, it's definitely more complicated and less aesthetically pleasing than Bear.
