Plugins are great, but I personally need hardware for tracking.

Especially with singers, "low latency" is nowhere close to "zero latency". Seriously, just take any vocal track and dupe it and delay by 2ms...In my experience, singers just get worse at controlling pitch and timbre when they have a short delay between the sound being generated inside their own skull, versus what they hear in their cans.

If I want to give the singer a headphone mix that already sounds like a rockstar with zero latency, then I need to do it outboard. And for me, once I am committed to that, I want it for everyone else, too. I want the whole band to hear in their headphone mix the same thing when tracking that they hear upon playback, with zero latency, so that the playback sounds exactly like what they heard when tracking. And for me, that means tracking through a console and outboard.

For mixing, I am pretty much 100% in the box these days, just because of modern expectations about recalls and budgets. And modern plugins sound great. But if I am tracking with the expectation that the tracks will sound record-ready, then I can't imagine doing it without outboard and a console.
