<p>Hmm Lets see:</p>
<p>Size: PSU has 2x more undergrads then Pitt which means its average stats has to be lower. Its the state flagship school so, its job is to educate state residents. </p>
<p>Merit Aid: PSU awards very few merit aid whereas Pitt awards a lot. Both award around same amount of need based aid. You will find people with 1600 SAT to 2100 SAT at PSU but at Pitt you will find 1800 to 2100. </p>
<p>PSU might have more reputation for Business and engineering, so I recommend Penn State. I highly doubt you will find any difference in the quality of education between those schools.</p>
