I shopped out a really nice Card whiz for a friend a couple of years ago, his dad bought it from an operator in 1979 & it sat in his climate controlled basement ever since. Very very low play game, cleaned up great. Zero playfield wear.
Anyway, of course I had to play test it at home for a while... after having played both this & Tim M's sweet Top card @ the NW pin show I would say it's close, but the drop targets put Card whiz on top.
