I still have a cd with msfs from 2 decades ago which was the last time I've used it, however back then I didn't have knowledge that I have now.
The reason for going xplane was the local flying school use it for sims (I think version 9 or 10), so decided to buy xplane for practicing at home.
There were glitches both in "$ertified" xplane as well as in home version 11, but the latest version 12 was literally useless (unless you are flying autopilot, which you won't at the IR check).
Latest msfs has better scenes/graphics, but really haven't played it much. I think msfs is more of a game vs xplane is more of a sim.
I am hoping they will fix the xplane12.
