PF3 works fine for me in MSFS 2020. I bought the PFEtoXPlane plugin in the hopes to duplicate the functionality of the one into the other.
The question becomes, "How to bounce between the sims seamlessly while using the same single install of PF3?"
Is this doable?
I get database grumblings when I try to use X-Plane on MSFS2020's database--and rightfully so, since I think X-Plane's AIRAC data is antiquated, and in fact at least one of the frequencies didn't 'line up' with what the 'helper' program in PFEtoXPL thought was a correct frequency.
It's also entirely possible I don't have a handle on how any of this works at all.
I'm worried that I'll overwrite my MSFS data if I use the techniques described in this video:
