Should I transfer?

I’m currently a student at the College of Saint Rose and was accepted to the University at Albany. I’m a political science major and am stuck on whether I should transfer or not. My main reason for transferring would be the opportunities at UAlbany (many more courses, political science honors societies, etc), but I feel as if I would be another number for professors. The main reason I would stay at Saint Rose is the close relationships I have forged with my professors and smaller class sizes.
Ultimately, it comes down to 2 things-- Is it worth it to have broader opportunities, or stay to have close relationships with professors?

What grade will you be when you transfer?
