It is worth noting that the port of UMK3 is for the 360, and not playable on the old xbox. From what I read, it plays awfully close to the original, both offline and online: Just a few minor issues here and there. Someone let me know how it is, I don't have a 360, and no MKA special addition like the PS2. As for the other ports, the PSP ones are full of inherent loading times at almost all points including selecting fighters. The exception is MK1, which is surprisingly close to the arcade product with almost no loading screens at all. The consel ports are way better about this, but are flawed in other ways as with the PSP ones. The audio in MK3 is quite muffelled, and I don't think there is a way to do the down+start thing in MK@ for Smoke do to button mapping. Also, I don't think Reptile is in the Deception port of MK1. I have no earthly idea why they would remove him, at least on purpose. Other than that, they seem to be fine.
