Congratulation on you first cruise! Seeing as how it's your first cruise there's no way to compare different cabins. I've been on the Oasis and Allure and now they're my favorite ships. I was on deck 14 and on deck 8 and found deck 8 a better location. All the balcony cabins are the same size. If you get the extended balcony it will be a couple of feet deeper. If you were going to spend a lot of time on your balcony it would probably be worth spending a little more for it. What ever you decide your going to have a wonderful time, and like me, get hooked on cruising.
