got forced to use BoA when they bought LaSalle Bank (domestic arm of ABN Amro) and wow does BoA suck. you cannot even compare their online interface to Chase, Chase's is vastly superior.
BoA sucks so bad that LaSalle Bank was awesome in comparison. if there were one US bank i could make collapse it would be BoA: it has awful customer service, crappy online interface and is run like a giant turd.
nothing quite like waiting 45 minutes to make a fucking wire transfer at a branch. employees turn over at their chicago branches more often than any other bank i've ever been to.
