If you were an early adopter of FB it was exclusive to college students and had a much, much more "mature" audience to myspace. That factor alone attracted a huge crowd that myspace couldn't touch. In terms of UI and whatnot, myspace never really forced/required users to use their real name which I also feel gave FB a huge advantage going forth. The rest of the UI myspace could have copied though (but by that time it probably was too late).
