If the Evernote sale has the dire consequences everyone expects it to, then the note-taking space is wide open. After ten years with Evernote, I migrated to Notion a few months ago and am heading towards another migration unless Notion starts to feel better to me soon. There are a lot of note-taking apps, but no gold standard yet.
Someday someone will produce a polished app with quick search, sync, and navigation, and all the popular features implemented in a way that imposes zero cognitive overhead if you don't use them. Most of the apps seem to be competing to figure out a unique killer feature or a unique experience to distinguish themselves from the pack, but I think the biggest winner will be the one that is just quietly better, a little bit smoother and quicker, that looks like it has no features at all except the ones you need.
That's an incredibly high bar for design and implementation, but somebody is going to hit it eventually. Who knows, maybe it will be Grug Notes!
