I have been using FS9 for years, I am behind everybody else because I am still using it.  My reasons, it is stable, I have a ton of payware that would be useless if I switch.  But with the support for FS9 dwindling and the lack of new products and updates I have been contemplating switching.  Trying to get an idea of what simulator to do?

FSX?
Prepare 3D?
X-Plane?
Others that I have not heard of?

So which one is better?
I would intend to buy good realistic aircraft and sceneries possibly a good weather generator.  Which one is a stable platform and which one is not.  Please let me know.

I'm only a GA single Engine Land rated pilot with limited hours but have had a sim for upwards of 15 years. I recently ran across the Oculus Rift coupled with X-plane and found it to be quite advanced from my days of multiple monitors. It takes some computing power but seems well worth the investment for such a small footprint.

I ran across the Oculus at a demo and was sold immediately. There is another VR system that boasts some advantages over the Oculus. HTC Vive Pro Eye, detects eye movement for faster control ability for gaming, but the screen resolution is what has me interested. With the exponential improvements in graphics, VR systems are taking flight simulation to a more realistic level.

Finally, there is the ability to add a copilot. Simply put, the copilot, a real person, is either simply a voice in the aircraft with you, or you can construct an avatar for both yourself and the copilot. The one restriction is that the copilot isn't allowed access to the controls.

Hope there was something in that that helped
