Used a credit union years ago when I lived in Allen, until they sold out to a bank.
Used Wells Fargo while in Aggieland, still keep a small amount in a checking account as a fall back.
Switched to RBFCU a few years ago. Better vehicle loan rates than just about anyone, any assessed fees usually are smaller at credit unions versus banks (in my experience), just seem to get better all around service. I know this does not seem quantifiable, but it is my experience.
