Although not the purpose of the tech alpha, we do see some of the new capabilities of the sim that will be available upon release. I have made a quick comparison of the takeoff phase (in both zero wind and strong crosswind conditions) and some stalls in both sims. 

 

The video starts with a takeoff in zero wind conditions. MSFS2020 is set to the realistic turbulence preset. Note the improved ground "traction" in 2024. As I fly over, you get a look at a quarry. This may be a coincidence based on what data is being used, but you can clearly see how much better it looks in MSFS2024. I then do some stalls and there are big differences. Note the "snap" in MSFS2024. Lots to discuss here.

Finally, a crosswind takeoff. Both sims are set with the wind from 271 degrees at 15G25 (takeoff runway is 23). In MSFS2020, we actually start spinning. I purposefully use no aileron to counter the wind. Notice how in MSFS2020 there is no issue at all, whereas in MSFS2024, the aircraft clearly needed it. This next example is not in the video, but showed a similar difference. Landing with 15G25 as a quartering tailwind, in MSFS2020 there was little effect, whereas in MSFS2024 the aircraft kept being lifted up from the back-right side, exacerbated by rapid breaking.

Of course, much more in-depth comparison should be done, especially once the final version releases, but I wanted to show this quick comparison for everyone to discuss, whether good or bad.

Thanks for putting this together.

 

But there's people who say there's little or no difference between MSFS2024 and MSFS2020's flight models! 😂

Seriously, thanks for doing this.

Thanks for this detailed report and comparison video!

Are you finding any of the issues reported by the OP in this thread? https://www.avsim.com/forums/topic/651279-flight-model-comparison-2024-vs-2020-unexpected-results/

Ground handling is much much better, considering how bad it was in 2020, i guess it was hard to make it worse, but in flight it's still heh with these planes.
Alec here is explaining very well

Also, no offense, but these stall demos were not really good, it was more like spin demo than stall, not coordinated at all. Cessnsa are quite gentle in the stall if you properly manage the rudder. Also do not use ailerons but rudder.

My testing is quite limited. In the specific areas I compared, I think MSFS2024 TA is better. Based on Alec's testing in other areas, I tend to agree with his assessment there. The thing that's hard for me to translate to the sim is the fact that IRL there is increasing resistance when moving the control surfaces. So, at home, it's much easier for me to instantly input right rudder, and the sim will immediately respond to that input. The lack of feedback in the sim makes it difficult for me to compare in those scenarios, especially when people have different sensitivity settings. I do use curves because otherwise it doesn't "feel" like real life, but that itself is subjective. I would say that from these two tests, I liked what MSFS2024 shows. Things like the crosswind behavior, for example, cannot be masked with control settings. Thanks for the test @Alec, the more direct comparisons the better. It should be noted that MSFS2024 is supposed to come with methods that allow us to quantify these feelings, so once we get the full release the picture should become clearer.

Regarding the stalls @Muds, I was rushing because I did not have much time earlier and did not adequately explain the test. The behavior shown in the video was the intention. Specifically, I wanted to see what would happen in both sims when there is a slight bank during the stall and you keep trying to prevent it with opposite roll. I just wanted to let people know what's in the video in broad terms. I will try to be more specific in the future. The standard power-on and power-off stalls are much more similar between the two sims than the actual test shown in the video.
