Sorry to dig up an old thread but I am about to sign up for one of these cards. I am trying to decide between the "Interest Checking Plus" and "High Yield Investor Checking." What is the difference between these 2 accounts? I would rather not have an investor account open that I don't plan on using if it isn't necessary. From what I could tell, both accounts are free with no minimum balances, and unlimited ATM fees anywhere in the world. Is there any benefit the High Yield has that the plus doesn't?
