What’s the most stable scenery generator these days?

[Ivo de Colfmaker]

Hi,
A bit on a slippery slope, but what's the most stable and smooth scenery generator these days?
In the past used P3D 3.5 , then moved on to xplane 11, but neither of them gave me a good experience.
RWY misalignment on landings being the biggest on. And stutters.
And the clouds on Xplane, brr
So whenever I flew PSX , it was stand alone .
I do not have FS2020, it seems that there some big problems for some people, not even possible to use it without CTD
 
After watching the stream from JP must say I am tempted  to give it a go.
Do you guys think it is worth it to invest the time ?

For stable all depends on your system to be fair, I have a low to moderate system using x-plane 11 and msfs2020 bot give good results with good frames unless in poor weather but still not stuttery that makes flying unenjoyable, I would say if you have x-plane 11 try using vulcan you would probably see a big improvement compared to a year ago.
