Hmm maybe, I'm less familiar with SNK fighters to a point, but the few I've knocked off not quite but somewhat similar. SNK bosses just react really fast and go nuts or spam if I remember. In SF4 it's more like takes it easier first round, then 2 and 3, the boss will often just suck you inside or spam another blow out move or two and finish you in moments. My memory is fuzzy with it as I hadn't bothered since the original SF4 release.
