I have always wondered which simulator people love the most.
Let's talk about these 3 sims:
1. FS2004 ACOF
2. X-Plane
3. Orbiter Space Flight Simulator
However, everyone has their own taste for realism, performance, and add-on developement.
I like FS2004 when it comes to visual realism [weather, flight models, scenery]. However, I don't like it when it comes to making the addons for it. For those of you who make the addons, you know how frustrating it can be when you load your own model and you see it bouncing around on the first try. Or when you create scenery.
I don't know about X-Plane because I don't have. However, I have read a lot about it when it comes to making addons for it.
I also like Orbiter because it is extremely flexible, has a small and simple folder structure, relies on pure realism [in terms of learning], and is easier for the addon developers [in a way].
