If he had to choose, I think Tex would rather roll the B47
If I did it right (not likely) the thrust to weight ratio of the B52 is only 30% greater than the B47 and the drag coefficient is obviously greater. Top speeds are about the same.
(Why would they not print rate of climb specs?)
I'm partial to the B47. We have one here at the Museum of flight in Seattle and "SAC" with Jimmy Stewert is on my favorite movie list.
