Which Student Loan Provider is Best?

I know most people on CC are against student loans, but I truly will need them, since my family is so low-income. I'm not going to take out tons of money, and my mom will be willing to cosign. I was wondering which student loan provider is best. I know of Sallie Mae, but I've read awful things about them. It did seem that most issues weren't the fault of Sallie Mae, it was more that people were taking out unaffordable amounts. My guidance counselor recommended them, but my favorite teacher told me their interest rates are incredibly high. PNC student loans offer an interest rate at 0.5%, but this requires automated payments. I know my bank, Wells Fargo, also offers student and parent loans. Interest rates are about 3-4%. Which provider is best, and why?
