Obsidian is described as 'Note-taking app that lets you create a personal knowledge graph with ease. It is designed for non-linear thinking and allows you to easily link your notes together wiki-style' and is a leading Note-taking tool in the office & productivity category. There are more than 100 alternatives to Obsidian for a variety of platforms, including Mac, Windows, Linux, Web-based and Android apps. The best Obsidian alternative is Logseq, which is both free and Open Source. Other great apps like Obsidian are Zettlr, sNotes – Students Notes, Joplin and Anytype.

I have over 5,000 notes in Bear which were easy to export to Obsidian (except for creation date order). Bear is still easier to use for non-technical users and has a WYSIWYG editing experience, which is lacking in Obsidian. I am currently testing Obsidian, as it is cross platform, has more features and free sync options.
Bi-directional linking and tags might be the only thing that relate these two, but it's more relation that every other entry on this list.
