I've decided to register after seeing this thread. It's great to see this issue being discussed somewhere.
Although I don't own 2024, I have flown the tech alpha and have watched many streams as this behaviour absolutely is noticeable across streams and videos. I do own 2020 which I picked up when it launched.
Having flown a real Cessna 172, that's my only baseline to compare against. MSFS 2020 has always been extremely twitchy, wobbly and sensitive on pitch across all aircraft - including the C172. It gets worse with faster speed with heavier aircraft that fly like they're near weightless.
It was very disappointing to try out the 2024 tech alpha only to discover the same issue with pitch being far too sensitive even with 25%, 50%, 80% and 100% curves on a Honeycomb Alpha, Boeing TCA Yoke and on a RealSimulator FSSB. That same behaviour is more than obvious in any streamer videos that I've seen from Squirrel, V1, Kip,
While I appreciate different hardware will behave differently (hence why I tested 3 that I own), if every other game/sim (X-Plane, DCS, IL-2, Falcon BMS) behaves as expected across a variety of aircraft while MSFS demonstrates a silly twitchy behaviour on all aircraft - that ultimately is a problem of the one sim, MSFS in this case.
Incidentally, the A2A Comanche is the only aircraft in 2020 which flies like an actual plane.
