Best credit card to use for daily spending

I have 3 main credit cards I use:

Chase freedom unlimited

Chase Sapphire Preferred

Amex Platinum

(I also have capitol one venture one card that I keep in wallet but don't really use)

I use all the benefits with the platinum and I will use it to pay for the resy restaurants, however since the chase freedom unlimited is 1.5% cash back on all purchases- I should be using this as an everyday card, right?

I am also thinking about getting the chase freedom flex for the rotating categories (however, I don't want this to be the spend more than I usually do)
