Bank of America (NYSE:BAC) has had a tough run over the past decade. Just looking at the bank's stock chart will cause the long-term investor to cringe.

The reasons for this horrid run are plentiful. There was the real estate bubble and the financial crisis. There was the unequivocally terrible Countrywide acquisition. There was Occupy Wall Street. And most recently the bank had to restate its capital calculations due to an internal spreadsheet error.

On the other side of the coin sits Wells Fargo (NYSE:WFC), the largest U.S. bank by market cap and the gold standard for banks from coast to coast. Wells handled the financial crisis like a mere speed bump to its rise to the top of the investing world. Through some combination of superior management and old-fashioned good luck, the bank has sailed through the past 10 years unscathed. 

Ask any bank investor out there which of these two megabanks is the best and most would say Wells Fargo.
