Thanks! I'm kinda repeating myself but major differences:

1. Text Replacement enters the text and _then_ replaces it which for me is really distracting.

2. It has this little pop up even for a single option which is also very distracting.

The benefit of it however is that it's more stable (as mentioned in README so apps ignore user keybinds for some reason)

The other plus of text replacement is synchronization. I have a bunch of LaTeX style symbol names mapped on my Mac but they work just as well on my phone. I’m typing this on a phone and \Omega is automatically replaced with Ω or a favorite of mine \shrug becomes ¯\_(ツ)_/¯.

I also spend time on Windows and nothing seems to come close to this convenient (win-. has a few useful things like the character picker panel in macOS but to get more, tools like autohotkey feel really cumbersome).
