Ally.
I moved from Capital One to Ally when Ally started beating them by a lot in rates. Now I'm too lazy to switch, but I also noticed that while Ally does not always have the #1 rates, it is almost always near the top. They don't seem to do the bait and switch thing with rollercoaster rates -- top of the tables to get accounts, then the bottom when they don't care. Rates are consistently good, usually just a hair behind whomever has decided to be the temporary market leader.
Also, great website and ease of use (e.g., can transfer $$ between checking and savings instantly with a couple clicks), good mobile app, good CD rates. All with one login.
Very happy with the experience and no plans to switch just for 0.2% or something in interest at this point.
