Q50 > IS for me. I love the new headlights, love the aggressive front. The car is packed with tech; i know some people don't care about that. I'm just a bit disappointed that it is still on the VQ37 engine. Wish they got something more powerful in there. Might have to look into one of these as a daily in the future.
Edit: Also hate that it doesn't have a 6MT option. For me if it isn't a DCT, it needs to be 6MT.
Edit Edit: OP I don't think the pictures do it justice, like most cars it should be seen in person. Here's a "review" I found on youtube. Kinda boring since there isn't any driving but it shows off the features very well.
