I have only used RealFlight. I am thoroughly happy with it.

However, since you are in Europe, I suggest you take a look at the Reflex IVOL system. The Reflex looks really outstanding from what I have seen in previews and I know there is a huge following in Europe with several websites dedicated to designer models being created. The new IVOL controller also looks quite amazing. However, it is rather expensive but if you can afford it..........
