Ummm....it's actually "wiz wit" vs. crawfish ettoufee.
I've had good cheesesteaks from both Gino's and Pat's (my favorite) and I've had great food in New Orleans. Personally, I would go with the food in New Orleans because a half-@$$ed cheesesteak is still 100 times better than fake cajun/creole food.
I'm going to Tulane next year because I really liked it and it was the only place I got in. So my choice was easy. If both are the same price and your family is just as far away from either, then flip a coin. But there are a lot more resources - parks, mountain, non-corrupt local governments, grocery stores around TJ and Philly than I think there are in NO. That said, I prefer NO over Vegas for fun and I'm from Baltimore so I automatically hate Philly.
Word.
