Chev Monte Carlo or Pontiac Grand Am?

I have a 1995 Chev Monte Carlo V6 3.1 L with 224,200 miles on it. It has a blown head-gasket. I am thinking about trading it for an 1997 Pontiac Grand am that has a Quad 4 (4-cylinder) engine that has 176,000. My question is which one has the better engine/is the better car? I have heard mixed reviews on the Quad 4......PLEASE ADVISE!!!! :confused:
