The Prometheus may have been ugly, but it was my favorite because it was Earth's first. It was kinda janky and totally experimental, but it was absolutely a necessary step in our advancement of science enabling better and cooler ships like Daedalus. It was usually outgunned and outsized by everything it went up against, but still managed to leave a mark. It saved the day in the battle of Antarctica enabling the discovery of Atlantis.
Do I think it was a better ship? Of course not, it was totally inferior (and ugly). But it made for a better story. For a good portion of the show it was all we had and it was barely enough, but it became more of a character than a tool. The moment the Prometheus was blasted in half was just as serious as any character death (and not just because of Pendergast). It was a huge blow to us and let the viewers know the Ori were a real threat.
I'm either going to be a badass or a dumbass.
