On the quality vs. quantiy issue: The Tigers were meant to be built in low numbers. The Germans never did get around to rationalizing it (both models) for mass production. The Panther, on the other hand, was designed more for mass production. Despite it being a totally new design, being rushed into service, and of course, the Allied bombings on production facilities, somewhere aroung 6000 of all types were produced. This wasn't too bad, considering all the above factors. Therefore the Panther was made for combat quality AND quantity.
