OP here. I finally ditched Evernote when they made the Mac app Electron. I've tried Obsidian but it didn't stick (and it's Electron), but hear very good things about it.

I decided on DevonThink since it closely resembled what I used Evernote for but ditched it after just a month due to to bad iOS apps, weird default formatting issues, hostile developers (license covers max 2 computers, and refusal to support a few basic things).

Stumbled upon Ulysses and I've been using it since then. Excellent plain text/Markdown support (you can turn off the markdown formats you don't want to use), sensible default fonts and such, fast and native Mac app, great iOS apps, etc.
