A raging debate, to be sure. Personally, I like the ATIs more. It's just easier to make power with them I think. Vortec does offer an aftercooler, but it costs $1200 extra and seems to be a total pain in the @ss to hook up (it's water-to-air so you have to wire up a water pump and whatnot). I've got a few friends who have ATIs cuz their headquarters are about 10 mins away from here and I've helped install a few. Not quite as easy as a Vortec install, but I think you'll be happy you spent the extra time.
