Because the Nintendo 64 hardware handles data in a Big-Endian format, choosing a .z64 file allows emulators to bypass an extra translation layer. Modern emulators like Project64 or Mupen64Plus can instantly read the code.
If your comparison is actually between the and other regional releases like Japan (.j) or Europe (.e), the US version holds distinct advantages for most players. USA (.u) vs. Europe (.e)
