I'll be the oddball who hasn't had any issues with BoA, but I'll preface that by saying my cards from BoA are from 2021 or earlier. If you have $100K (3 mo avg) in assets you can park at Merrill Lynch, you qualify for their Platinum Honors tier and get a 75% boost over the regular cc rewards. At that tier, with the BoA Premium Rewards card you could get 2.625% cash back on all spending, and 3.5% back on travel & dining. It currently has a $600 SUB for $4K MSR, and $95 AF and a yearly $100 airline incidental credit. Based on recent comments here, I think this would be an option only if you have a nearby BoA branch where you could go in person if you needed to. This is a card I opened in order to have the easiest and most cash back from normal spending for a non-churner. That said, since I'm routinely opening new cards, I rarely ever use it.
Going the Ink Cash route and getting no-fee prepaids at office supply stores will get you 5% cash back at a minimum. I do find the bookkeeping portion of this annoying, but I will still do it depending on what my goals are at the time.
