In my experience as a cyclist and from what I've read in various books, the straighter the frame tubes, the better the bike handles and, more importantly, the better it endures heavier loads. The classic geometry is 2 triangles for this reason. The Scott pretty much has it, but the Wilier not so much. If you look closely, you can spot that the top tube makes a slight curve downwards right before reaching the seat post. Also, even harder to notice, is that the seatstays are actually curved slightly. Take an object that has a straight line and put it next to these tubes, you will see the curve.

Now many people would wave off such worries by saying that technology has made such things possible, etc. I don't disagree with that, I'm just saying that I personally prefer the classic geometry that the Scott has, since I feel it'd ride better and be more durable in the long run.
