I wasn't a Typora user, but from what I can see after playing a bit with the macOS version a few major differences could be:
- Notable has better notes organization thanks to indefinitely nestable tags. I think one organizes notes in Typora by organizing the directory structure? That's fine but limiting as one can't really put a note into 2 folders at the same time (maybe Typora supports symlinks though, I'm not sure).
- Notable comes with multi-note editing, which is cool for tagging/pinning/starring multiple notes at once.
- Typora is way more customizable.
- Typora feels more native to me and starts up faster.
