I switched to Joplin a few years ago from Evernote and haven't looked back. Take control of your own notes - Joplin is open source and has clients for every platform, and imports notebooks from Evernote.
Haven't tried Obsidian, but have heard good things about it. I have about 12,000 notes and continue to be impressed with Joplin's ability to handle that with no issues.
Different use cases, indeed. All I need is plaintext, images, and in-line pdf rendering. No audio, no video, no LaTeX, not even italics or bold.
Now, to be completely fair, while Joplin is great for simple notes, it’s data entry modes are weird AF. I assume, in a programmers mind, the operation is normal for an IDE as it can’t/won’t render links/objects in line with editing. You either get a markup-only window that’s editable, a rendered window that is read only, or lose half your screen to a split-view version. These options are selected via two, separate, unlabeled, non-status-indicating toggle buttons which cycle through 2 and 3 versions if the view.
