The thing that really surprised me about those two bikes is that I preferred the falcon. Both climbed well, both took pretty well to 650b when I tried that but with 700c the falcon was the clear winner for it's greater room for tires. The Miyata always built up a touch lighter and that short top tube was nice on my arthritic neck. Now back to your original question.... I have no idea...
