I recently switched back to Pro Tools for mixing.
I used to use it for a while, then go back to Ableton Live due to some changes in Live, but I’m back in the PT land.
This video is about why I’m doing it.
I want to emphasize: this is only for mixing. I’d never suggest PT for making music, as Ableton Live excels at that.
I’m still also doing all my mastering-only projects in Live, for which it works well.

See the video info field for a full list of things where I feel PT takes the cake compared to Ableton Live.
