In other words - fitness matters more

-40, I'll take those back.
Here's 2 bikes I own.
16 pounds, rides like a dream. Absolutely brilliant ride. Yes, I know about my seatpost btw.
24 pound steel bike. Guess which one is faster? Same rider, but there's an extra 8 pounds I'm lugging around on the Bianchi. But you need to cough up some dough to make it worth your while. 16-17 pound fixed gear is very possible with $1000.
It's not just weight though. Stiffness makes a big difference, also geometry and the way you want the bike to feel.
