I'm usually in an aisle seat, and I stand up pretty much first every time. Not that I'm in a huge hurry...I'm just tall and would rather stand than sit there in the little seat for an extra 10 minutes.

Sometimes if there's a gap in the deplaning queue, I'll take it. If a guy in the row in front is dawdling and I can exit without impeding his progress, I do it. Happens occasionally if the window pax are slowpokes.
