Trust me. QBs still are incredibly important. I've played with these rules for 3-4 years now and I've often considered grabbing a top QB in 1st or 2nd round because of how big a difference they make in a team. As I'm sure you've experienced, there are games where guys like Brady or P. Manning will have you cursing the other team hahaha.
You don't have to convince me. I've played in leagues with both scoring systems. It just changes the draft strategy.
As I said, I'm fine with either.
