what reproduces the original Capcome arcade games more faithfully: Capcom Classics Collection on Xbox, or playing those games via XMAME on Xbox?

I heard that, with the exception of 6 games (i.e Final Fight, Forgotten Worlds) these are ports of the Playstation version of Capcom Generation collections of the late 1990s, which were not 100% identical to the arcade games although pretty close.

would I be getting a more arcade-accurate experience playing these games via MAME on Xbox ?
