I find sim flying more difficult than the real thing if that's any help. The fact that you are getting all sorts of feedback from a real aircraft makes them easier to fly IMO plus you're not looking through a 20 inch letterbox, you have peripheral vision, instant views of wherever you want and far better visual feedback from real world flying.
I have a quite highly regarded gliding sim called Condor, I can crash to order with that but in 20 years of flying gliders I've never had an incident. I'm the same with R/C aircraft, damn sight harder to fly those than the real deal.
