Is it better to use a mortgage broker or a mortgage lender?

A mortgage lender is a financial institution that makes direct loans, while a mortgage broker does not lend money; the broker finds different lenders or mortgage loans for a fee. When you work with a broker, you pay a loan-specific fee for that service. Some financial institutions operate as both lenders and brokers, so ask whether a broker is involved in your transaction, and shop around for the best loan terms either way.
