Win is the best version by far, Roor, himself, has said so. As for stability, I would tend to think that Win would also be the most stable. This, since it has had a lot more developement than the DOS version. As for comparing to ePSXe, uh, uh, not yet. Adripsx is a very good and promising emulator, but it is not yet up to the level of the current version of ePSXe.
