No offense, but who cares? People should be lucky they GOT an arcade port for each system. Back then, players were WELL taken-care of, they were mostly ensured they would get a port no matter what system they gamed on. Nowdays, if they even BOTHER to port an arcade game, you get whatever system the arcade translates to best (IE: Most SEGA arcade games use 360 hardware now, meaning only 360 gets the ports).
Ironically, I actually find us OLDSCHOOL gamers more spoiled and jaded, because hell we were! Game companies actually GAVE A SHIT back then! Nowdays it's "we need your cash, not you".
So instead of arguing which port was better (which I will admit, is compelling) just think about the time when you could be a SMS fanboy, and when a rival system owner taunted you with a game you "weren't" getting, you could counter-retort "Au contraire, my friend", likewise for other systems.
