Tekken IMO got bad after the years went by, I still have tekken 6, but it's not even hard to pull off a lol juggle combo that'll do +50% damage, in general if you're launched in the air, youre dead. BlazBlue isn't noob friendly with power skills and juggles that are jawsome. Every char is personalized. But if you're wanting an easier game without much work, go with tekken 6, it's pretty fun and mainly casual playing with no steep learning curves (or w/e they were called lol).
tl;dr If you want a game you'll have to milk for your experience, BlazBlue, if not, Tekken.
