Could't agree more Rob.
The thing that I want to point out is that even if you see problems with P3D, you are talking about a platform that is being actively worked on. There is a group of software engineers/developers being paid to make it better, faster, stabler and did I mention better. FSX has a tons of add ons and can me made to look great, but the legacy code is stuck in it's tracks.
I started with flight simulator in 1986 on Atari and have embraced every new version, I see no reason to stop with FSX. Good times!
