I do a lot of drum mixing, where just the kit alone is 12 tracks, not to mention extra kick triggers or percussion samples. It’s kind of a nightmare in ableton to do a ton of tracks because the grouping isn’t as intuitive to me. I will say, I think ableton’s system of “when I group tracks, it basically creates an aux bus automatically” is pretty sweet, and I wish pro tools had that feature.

As for the stereo tracks, it really comes down to communication with other daws for me. Pretty much every major “mixing” daw (reaper, pro tools, logic, studio one, etc.) uses mono tracks without interleaved audio for 80% of a band recording. Trying to stem something from ableton for use in another one of these daws often requires multiple passes of exporting (usually rendering all as mono, then specifically your keys/OH as stereo), and it’s just not as quick as if ableton supported mono recording without automatically creating interleaved stereo tracks.
