I just purchased a '98 with a 4.2 and a friend has had a '97 with a 4.6. I'd be willing to pay a grand more for the 4.6 if I had it to do over. The 4.6 gets seems to get better fuel milage than the 4.2 I have. He seems to get about 3mpg better than me so I could make up the difference in cost rather quickly. As far as the 4.2 itself it seems like an adequate motor for me so far, although I don't ahve to tow anything. Like I said I've only had it a short while so I don't know how hard you can run it into the ground.
