If anyone else completely understood what LionX just said, we need to be friends.

Just to defend SC a bit, Guard Impacting is not cheap/infinite defense either. You do have an advantage after performing it, though the person on the receiving end is not defenseless and can retaliate with their own parry (and makes its own little rock-paper-scissors gameplay). Which may be what you're referring to, since SF3's parrying will essentially give you a free attack where SC still gives you a chance to defend yourself.

DOA's was cheap though. You could have a reversal attempt after every individual hit in a combo string as long as your feet were on the ground. You are punished by taking increased damage if you guess wrong, but if you get good enough to exploit it fully it is really cheap
