Only 1 person failed my calc class. Over 70% of my stats class were folks who had previously failed the class - one had failed it seven (yes, that's SEVEN) times. Lest you say the professor sucked for the stats class, both classes were taught by the same professor, and he is absolutely brilliant, straightforward, helpful, and has a gift of making the horridly complex be absolutely simple to get through and remember.
Oh, and 25% of my stats class failed (yet again in many cases).
I say again, depends on how your brain works. If calculus is a good fit, take it. If you like doing tests on bunches of numbers (and in some cases trying to figure out what test to use), take stats. Calculus will teach you a different kind of math, stats is just an algebraic application (unless you take statistical methods class which requires extensive calculus, linear algebra, and group theory background - I don't recommend this one). I do agree that in most cases stats will be more helpful.
