I use RF to practice on, and setup a 10 MPH crosswind, which really helps, a LOT!  Once you get the hang of bringing it in with those settings, the real ones arent so bad, but the main difference between the sim and real flying is perspective, you dont have it on the sim, so landings will actually come easier to you with the real plane since you can see the runway while focused on the plane.  That is the one thing the sim just cant get right.
