Personally, I would find it annoying to frequently set up new accounts just to chase small percentage gains. I set up an account with ally and plan to just stick with them. Rates are good, not necessarily the best though. I’m not particularly advocating for them, just saying that’s where I am at the moment. I’ve not heard of ufb, but they might be good too. Also look at other options like CDs. They are less flexible than a savings account but can usually give you a little more interest (though the rate you say you are getting at ufb looks similar or higher than the best cd rates I’ve seen.)
Rates are pretty nice right now, but they probably won’t stay like this forever. Adding into your retirement account (invested in a target date fund or an index fund) is probably best long term, assuming you don’t need the money now.
