I have yet to have problems with the Credit Union. They've done me well time and time again. All in one day, my wife and I managed to get an account opened and a credit card. Their technology front is outstanding, with Android Pay and Samsung Pay coming quickly. A smart watch app came out shortly after.
Calling in is easy, transfering funds is even easier. The only problem I've ever had, was sending money to a non-CU bank took a lot longer than expected.
