I don't take mine to class, but that's because I don't go to school! I do use a rolling bag, and I'll be honest, I'm not sure "who" made it. I was looking for one that had good padding, could handle other things, and was lightweight but sturdy. It's lasted me about 6 years now!
Yes, I did start out looking at the "name" bags, but most didn't have what I needed. So, I just made my mind up that the name that mattered was the name on the luggage tag!
