Rory,
Unfortunately neither Dan nor Santino won but
Chloe Dao did. It was totally ridiculous. Her line was just plain odd. I believe she won because of the quirky inclusion of Debra Messing as the guest judge. It ruined the whole season.
I'm biased though because of my high admiration of Santino. He's a true artist.
Ok, so if you watched the first show tonight...
MAKE YOUR PREDICTION
as to who will win in the end. Pick your favorite as it were.
I choose Alison.
Her initial portfolio and her reason for attempting Project Runway were the most intriguing and impressive to me. She's a tad shy and naive but this life event for her could poise her for greatness. I hope so at least.
Laura was a close second. Her and Alison both I perceive as being artists. They were focused on design and design principles, not personal style or subjectivity.
Of course they both simply passed the first test. Neither of them won. That's ok. 
Keith is a soulless creep that happens to have an eye for design and Jeffery is about the clearest definition of pretentious as you can get.
I think this group is the oldest overall out of the three and the most full of attitude. This will be a very cutthroat show me thinks.
Edit: Just as a quick reference you can go here to see the current designers
