Grads from both of these programs are successful as performers after graduation. The training is strong at both...
I went to Syracuse for undergrad as a BFA MT and we did take all of the same acting classes as the BFA actors. This was one of the reasons I chose Syracuse many moons ago. I too was deciding between NYU and Syracuse... at that time CAP21 was not a part of NYU (and there was not a musical theatre studio that you could enter before your junior year), so I was deciding between an acting studio at NYU, and musical theatre at Syracuse and a few others. In the end I decided that Syracuse felt like the right place for me to be, the environment, the training, the people, the finances. I have many friends who graduated from NYU and they felt it was the right place for them to be.... it is a tough decision, but in the end only you can make it... it doesn't matter if everyone else thinks you should make one choice... if you feel right about the other, it is the right choice.
Ultimately, you have to decide the kind of educational environment, location, you are looking for... also consider the specific classes you would be taking.... what will your academic days look like at each school... how much of your day in studio classes, how much in academics, what kinds of studio classes will you take. Obviously, going to college in Syracuse, NY will be a different college expereience than going to college in NYC... do you have a sense of which one you might prefer?
Get a little more feedback from people, make pros and cons lists, then -- go with your gut!
You have great options! Congratulations!
