It varies from model to model.
There is no brand that can be labelled as "better for a student".
Generally speaking, I don't have a great experience with cheap Acer laptops. They certainly make good enough high-end machines, but the low end build quality seemed poor ever since I tried them. Lenovo's laptops have a good reputation of being a well built machines. Dell is know for their good customer service and owning a Dell myself, I don't have much to complain about it's build quality.
