RushFit or P90X??

Hi there, I'm a fan of DVD workouts and wondered if anyone had tried both of these DVD sets at all please? I'm not entirely sure which to get. I'm a 5'8" girl weighing in at 177lb so I'm overweight but not obese. My stamina is fair, I made it through 30DS and looking for my next challenge. I do also have moderate asthma. Which of these DVDs would you recommend of the two and for what reasons?
Thank you for your opinions in advance,
MK
