Is the Tucson all that much better than the Santa Fe ?

I have been offfered, by a Hyundai dealer, a substantial discount from
the sticker price of a 2005 (not 2007) Santa Fe. It looks nice and
works for me.

The Tucson is what seems to be getting all the press and the J. D.
Power approval ratings. Is there that much difference ?

Obviously the former year left over 2005 would logically be and is
being discounted. But is there something that much better about the
Tucson ? Or is it that the Tucson has just about everything that the
Santa Fe has, but at a lower price, and therefore is a better deal, is
more popular and would bring greater customer satisfaction in value
for the money, and thus a good Power survey response ?

Thanks in advance.

PS would any of you see (again) all that much improvement between a
2005 Santa Fe and or Tucson and a 2007 ?
