Credit unions are generally less profit-oriented. However, big credit unions can be just as annoying as big banks. I recently switched from the credit union I belonged to for many years because it kept getting bigger as a result of acquiring or merging with other credit unions and became more about "the rules" and less about the people. I now have my mortgage and accounts at a small credit union near my house.
I like credit unions better. I have always gotten better service and better rates thru them. However when my husband's job caused us to move a lot we went with a bigger bank so there would most likely be a branch near us. We have one more move and I think we will find a credit union after that.
