I would take the Audi. Quattro, nicer interior IMO, very balanced and weighty to drive. It'll hold it's value better (not that you care while leasing), and you'll save enough on scheduled maintenance. Plus I think the general public thinks more highly of Audi than Saab.
The Saab looks good, and those alloys really help it out, but it just isn't as upscale to me. Plus the dealer network isn't as comprehensive. And while I thought the Aero powerplants would be a rush, the turbo lag on them irritated me when I drove 'em. I think the 1.8T lag is a little less, even if ultimately there's less power. I'm sure the 9-3 feels lighter, so if you're into hustling it you may prefer that route tho.
