Your -3 degrees of camber is unrealistic to expect stock. In all the front DWB cars I'm familiar with, stock camber adjustment is far from enough for serious track use and all of them have aftermarket adjustable wishbones to cater for that use. Sure, DWB offer a much more favorable camber curve over MacPherson struts, but street cars typically lean so much into corners (relative to proper race cars) that the dynamic camber gain of DWB over struts isn't enough for track driving.
I've actually pondered a similar question to yours, and my conclusion is that any component comparison on a car is not black and white (in terms of "with DBW it would be better") but rather need to be treated more as a scale, where perhaps DWB can be potentially better than strut, but well sorted strut suspension can be just as good as well sorted DWB, and better than poorly setup DWB. One of the best handling sports cars (the Porsche Cayman) has struts on all four corners. Is a Lotus Evora so much better for having DWB all around? Or is it a matter of tuning and decision making when designing the car? Would the Evora really suffer that much if it had to use struts?

You'd need camber plates to get that much camber of course. Like you said there are lots of cars which are considered to be some of the best handling cars in the world (M3, Camaro, Cayman, 911) and they use struts. Surely they're not so much of a disadvantage assuming you can limit body roll to as many degrees of static negative camber you can get on the car, if they are at all.
The DC5 Type R is unequivocally faster than the DC2 despite struts vs wishbones.
