Totally agree. On any flight where there are multiple options, I select based on the aircraft type. Prefer the A320 series over the B737 for the wider seats and cabin. Like the B787 for long haul despite the slightly narrower seat in economy for the same reasons Russ mentioned. The B777 is just about bearable. Much prefer the A330. Go out of my way to avoid the B757/767 aircraft. Most are old and dingy now. LOVE regional aircraft (CRJ/EMB/DHC/ATR). Haven’t had the pleasure of the A350 yet.
