With a new fast video card the PSX and PC games look very similar. They look close enough that I wouldn't recommend one over the other in terms of graphics. However there are other things to consider such as the blur effect that's missing on the PC version, and of coarse ePSXe cannot play the mdecs w/o crashing. Right now I would rather play MGS on the PC and get all the cutscenes, but with time I believe that ePSXe(or maybe some other emulator?) will be able to play the PSX version perfectly.
