I'll be flip-flopping all week with this one. Already gone Brawn-Williams-Brawn. I think the Williams looks more like what a F1 "should be" but the Brawn's spartan paint scheme is rather refreshing given how I feel that liveries in general have taken a sharp nose dive in quality over the last decades.
Williams has a better front section.
Brawn has nicer sidepods and mid-section.
Don't like the Williams rear wing.
