First, I don't think the first one is so much better or well organized.
Next, I think it's very important to be as candid as possible without compromising your privacy or hurting your own interests. Truthful writing feels fresh and real. Lies always sound canned and stale, even when they are very clever.
So, it's not surprising that your more truthful essay is much more engaging. In that one, you sound like an honest and lively person with a distinct personality. The first essay, in contrast, could have been written by anybody.
At the same time, the second essay does have more errors and probably does disclose more than may be wise about your indecision. My challenge to you is to revise and clean up that essay, keeping the lively and honest tone. It's good that you are still questioning what you want to do. The undergraduate years are the years in which students learn what they are best suited to do. So, change the tone. Instead of saying "God, I don't know which one to take," say something about being excited by the possibilities and looking forward to the process of studying different subjects in order to, over time, learn more about yourself and the best way for you to make your mark in the world.
