First, you will be taking essentially the same courses no matter where you go. The US undergraduate curriculum is what it is, and it is largely common across schools. So is the 1st year graduate curriculum, so taking a few grad classes is also unlikely to be any different. The only difference is research.
Second, the quality of an undergrad research program is largely hit and miss. This is, rightly or wrongly, looked upon as "value added". It varies from university to university, professor to professor, and often year to year.
Finally, since you list Condensed Matter as one of your interests, you will find that virtually every school does that.
