Credit Union

+Lower loan rates — mortgages, auto loans, and personal loans are often cheaper
+Fewer fees and lower minimums — many have no monthly maintenance fees

Glen's Verdict

Former hedge fund manager, current index fund enthusiast

Use both. Seriously. Keep your primary checking at a big bank or online bank for the technology and convenience — bill pay, Zelle, mobile deposit, nationwide ATMs. Then open a credit union account for your auto loan or mortgage where the rate difference can save you thousands. Or skip both legacy options: online banks like Ally and Marcus combine credit-union-level rates with big-bank technology. The era of choosing one institution for everything is over. Use the best tool for each job.
