The only bank I had any experience with has been bank of america.
The experience was not as good as the the agents that responded before me. They were not sure on how to handle the process and there were delay after delay. Even when escalating it, there process did not improve. My buyer finally withdrew their offer and purchased another property.
It all depends on the bank and the processors level of experience.
Wish you Luck
