comparing canyon roads and road course seem like apples and oranges to me. i'd say, if GSS is indeed running at the track 2 times a month, his experience with the coilovers is very relevant and shouldn't be dismissed so readily. particularly not by an a$$-skidpad/slalom based on canyon driving.

tracks are generally smooth pavement and kept relatively clean. public roads have more imperfections; cracks, potholes, bumps. etc.

linear springs are preferred for the track/racing. the advantage being that they are easier to dial in, and more predictable, because the variable (spring rate) does not change.

progressive springs are better for street. they handle the imperfections better, less jarring, and therefore give a more stable feeling, which in turn makes people feel more confident. if you feel stable and confident you will feel like this coilover is better.

it's probably fair to compare coilovers (in this case the BCs vs KWs) in terms of quality of fit and finish, comfort of ride, whatever, but which one is faster cannot be compared especially when not even talking about the same kind of driving. in track driving you are trying to approach, and have the freedom to approach 10/10. in street driving, you better be shooting for 9/10s since there are just to many variables (leaving aside the fact that you are driving at illegal speeds).

the question remains, if you are going to track the car. which one yields faster lap times? this is difficult to ascertain since the equation is complicated by a lot of other factors (sway bars, tires, alignment, etc.)

so i suppose the point of my comment is... this conversation could go on forever and not reach a *valid* conclusion. however, it is important to note that linear springs are preferred in racing for a reason and that progressive create a better street experience. so it could be argued the KW V3s are street coilovers, while the BC BRs are a track coilover.
