BSN and ADN timeline difference seems to be the exact same

Other than cost and "school prestige" I'm having trouble understanding the distinctions between the two pathways.

My state's ADN program has about 40-45 hours of prereqs to apply for Nursing school. That almost makes you a junior by hours. Once accepted into the ADN program, it takes another 2 years. So 3.5 years total, assuming you get in the first round. (Which many people do not, so add some extra time to the average)

But a BSN is designed to be 4 years. So far at best, it's a semester difference.

ADN is branded as a faster track..but at best, it's a semester difference. As I'm going to finish up my prereqs this year I am trying to understand my options. Why would I not just apply to both?

Edit: I already have a bachelors and don't give a crap out "prestige" but that doesn't stop BSN programs from trying to market it that way.
