I think so far I will stick with p3d 4.5. The v5 is super unstable and many things are not out yet for it, including real light and True Glass. If you look closely at MS 2020 youtube play through videos, there is a bunch of microstutters still present when flying. It's not perfectly fluid. Hopefully that will be fixed. Still, its a bit worrisome. As an example: https://www.youtube.com/watch?v=ZqFaMi3wVbc
Look at 2:10 mark. When the airbus is turning to the runway. Looks like it will be a stutter fest allover again.
