Typist looks interesting, although I've had no issues with LaTeX so no reason to change to something more niche.

You've never had an underfull hbox?

Either your are a pro LaTeX user or you did not use the more advanced features.

Or I just didn't have the issues you or others did. Tex distribution can make a point, also editor most likely.
