FSX/P3D. To be fairly honest, I have never had any experience with FlightSimWare's products. I think this is largely due in part of the visuals. Not that they look bad, but just not seemingly quite up to par with my own expectations. And let's face it, in all facets of this hobby, we all have bench-marked expectations in terms of where we will and will not spend our money. That said, this team is gradually getting better and better on the visual quality standard and if what I have been hearing is true, FSW's aircraft are really true pilot aircraft similar to A2A on the dynamics and coding end. The MU-2B-60 is currently in development by this team and indeed it's no MilViz, but it's not bad either. Not bat at all.
