Honestly, I think the URs are better. And of course, any MSR card. I have BoA Plat Honors, and between DH and me, we have the Travel Rewards, Cash Rewards, and Premium Rewards cards. They see very little spend. The only one that sees any use at all is the Cash Rewards, which I sometimes use on Plastiq for mortgage (mine codes as travel category; I know people have mixed experiences with that). But it's no longer available as a MC. DoC is reporting some upcoming rumored changes to BoA's tiers and elite cc offering, so I'm keeping an eye on that. As these loyalty programs are showing a trend to switching over to dynamic pricing, it's more challenging to get the really amazing redemptions that were more common in the past, so straight cash back does have its own appeal.
ETA: I know you know your way around all the award redemptions, you are the queen of award redemptions. I only tagged you because you mentioned BoA, and it was an easy way for me to add thoughts about it.
