i've never used tor, but wouldn't it be better operational security to not use tor for banking to avoid being fingerprinted/identified, if one cared about remaining anonymous?
Fingerprinted/ID'ed by who? There is effectively no difference in security with tor when it comes to the end points. The main purpose of tor is to prevent anyone in the middle from getting any information.
All they'll get is a strong ID on your exit node. That node is, of course, shared by a ton of people and so trying to pick apart the traffic is going to be very difficult
