While many credit union members swear by the service they receive, there are still many reasons people choose to bank with giants like Bank of America (BAC -0.17%). In this segment from The Motley Fool's everything-financials show, Where the Money Is, banking analysts David Hanson and Matt Koppenheffer take a question from their mailbag about big banks vs. credit unions.

David points to Bank of America's advanced technology and ability to offer a one-stop-shop experience for customers. Bank of America allows a customer to have their deposits, credit cards, mortgage, and investment accounts all on one screen. Meanwhile, Matt notes how Bank of America and other big banks like Citigroup (NYSE: C) can influence customers because of their enormous advertising budgets.
