I would personally suggest to you (and almost anyone else) that you do neither right now. Go out and get a job at an actual established mid-sized company (ie: not just some other startup). Do that for about 3-4 years (not too long, but more than a year). It is extremely valuable (IMO) for both the MBA and the found-a-startup tracks to know what a "real" business is supposed to look like and work like. Learn about all the socio-political stuff that goes on in a typical organization Learn about sales, booking sales, recognizing revenue and other aspects of cash flow Learn about product design, development, testing, etc. Learn about manufacturing, shipping, operations, logistics. Basically, you get the idea. This experience will, again IMO, give you a far better knowledge (and financial) basis upon which you can then launch into your next trajectory. Trust me, you have more time than you are led to believe to found or participate in a startup.
