I took one once and I was blown away by how smooth it felt in flight.

Airbus are nervous, jiggly and constantly jittering along as the avionics happily acknowledges the plane is within envelope. Boeing planes feel more damped and they don’t remind me of my flight stress as often.

But the Embraer?! I flew one over the English Channel, windy and all that; and yet, it sailed along gently.

Hmm...I fly frequently (every month) on either Boeing or Airbus planes and but for the seat pocket card I'd be hard pressed to identify one from the other.

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.
