As the other comment mentioned, I also can't notice the difference between a A320 and 737, although flown on both massively. Of course, weather has a great influence. The worst turbulence in my life was over North Macedonia on a flight to Greece and from Stockholm to Oslo, both in a 737 (300 and 800). But I can't relate that to the aircraft, the weather was poor.
But I'm convinced I can feel the difference between them and the A321. Maybe because of the lengthy fuselage, but it always feels much more comfortable.
