1. Electron-based, and take forever to launch (even if they are "fast for an Electron app").
2. Little to no plugin ecosystem whatever. No Vim mode, etc (yes there's Vim itself, but that's not a great choice for a GUI window editor).
3. Commercial, and costs nearly as much as a full-blown IDE.
Notepad++ was (is) pretty much perfect. Sadly, its default look-and-feel is "light mode" and "Courier New", rather than dark mode and Menlo/Consolas, so I don't think it even exists for the newer crowd.
