OK this is a interesting match..i Love both games with a passion, i for the most part rather play street fighter rather than MK..but in a heads up match MK vs SF, mortal Kombat takes this..
Mortal Kombat has many more advantages than SF, One advantage is that Mk characters uses weapons, in the earlier MK games, characters like scorpion used a Battle axe, and in the newer games he uses a ninja sword. For the most part all the character has weapons, usually hidden can be reveled with a combo in the older games. the newer games using a weapon is a option, depends of wat kind of fighter style u prefer..
Another advantage is that MK has a wide variedly of powers... For instance, subzero can freeze people. And Noob Sabiot can shoot a cloud of smoke at a opponent to nullify their attackts for a few seconds. a bunch of the MK characters can teleportand fly as well like scorpion, millina, radian ect..
Another advantage that MK has is that some of the characters are gods, ex: Radain Shado Khan, Shang Sun etc...how are supposed to kill a god tell me.?
Mk has better finishing moves, the have the fatality (the coolest), animality(very cool), babyality(kinda funny), friendship(very funny) ect. street fighter has nothing like that, thats the reason why Mk is more popular with the younger kids now a days.
Now for the people that are sayin that SF has Akuma, well MK has freakin Lui Kang, probally there best warrior of them all, im not sure if Akuma can beat Lui Kang but is would be a good match up. a better match would be Ryu and Akuma vs Lui Kang, and Scorpion, its safe to say that they are the games best fighters.
You know wats a good game Marvel vs Capcom 2 🙂
