I tend to agree with the previous sentiment that if you're losing to a button masher, you're not all that good at fighting games. Granted, there are quite a few fighters out there that have really cheesy character balance, but in the vs. series, they're still beatable with pretty much anybody, as long as you know how to use 'em.
And granted, I like the vs. series a lot, MvC2 was definitely my favorite, and this one's good as well, but I'm much more a fan of the Alpha style. Ken is definitely my character of choice in that series (why did you mess him up in MvC2, Capcom?).
