In terms of looks, the base chassis of the W09 wins out. The livery may be boring, but the car has a nicer flow to it, and it doesn't have a typical 2014 ugly nose. This year's Ferrari is generally worse looking in every way compared to its predecessor, and the loss of the white Santander elements hurts the livery big time.
The Ferrari wins just by virtue of being a Ferrari, but it's not their most memorable car. It doesn't help that it's a pain to drive, especially in the rain, and the increased casualization of the sport has made it so people have generally fallen for the "FeRrArI hAvE tHe BeSt CaR :^)" meme just because of the engine (itself only being better because of the acceleration), which is beyond disappointing. It's basically a more boring version of the F2008.
