My impression is that all banks are pretty miserable to deal with when you travel, though I imagine if you move out of consumer-grade junk, that improves. I have a bank account (Navy Federal Credit Union) that got locked out when I used a cashier's check to buy a car (despite repeated assurances that there was a note in my account explaining the transaction in advance.) Unfortunately, their customer service is just a notch better than Google, with hold times routinely exceeding 3 hours, and lines periodically going dead; consequently, I'm going on 7 months without access to my accounts.
