I'm a graduating senior at Case, majoring in computer science and something else. I haven't actually had any interaction with any of the AI stuff, classes or otherwise. However, overall (with some exceptions), I've thought that the classes were a bit too far on the easy side. This includes grad level classes, and is especially true compared to classes in my other major.
One other thing: I'm not sure how much you've researched Case, but medicine is huge here. The medical / biomedical engineering type stuff is by far Case's strongest suit, and that has a pretty strong influence on... just about everything. All fields here have a lot of research that's very much biology, so if you like biology, this is a pretty great thing.
As for your other schools, just going by the U.S. News rankings, Syracuse is the other one you should be looking at. I don't know anything about that.
The people are nice enough to make it an entirely reasonable climate to do a Master's in, I think. Basically, I would say that if easy classes and research that is more often than not very heavily biology-related sound good to you, you should definitely come here.
