Are A bodies more popular than B bodies?

There's a whale of a difference between what is "popular" and what costs a lot of money and therefore some would say "more valuable". I think A bodies are actually more popular - that is liked and more interesting to more people, because they are relatively less expensive, more fun to drive, more successful at the drag strip. You still see a big following for 63-5 B-bodies by the straight line performance minded, but starting in 67 the A body was closer in size and weight to the older B-bodies so that's where many of the racers went.
