Ableton added comping in Live 11.
In my 20 years of using Logic, I've never felt a need to get into scripting. But one workflow I'd love to be able to bring to Logic concerns the library browser - Ableton is great for organising a sample library, I can very quickly add tags, drag into folders, rename and even delete unwanted sample material.
Ableton is given a lot of credit for being able to manipulate audio timing using warping, but Logic's flex-time facilitates a nicer workflow imo since I can do it directly in the tracks arrangement.
