Instead of the Marriott Brilliant (Amex), does anyone have thoughts on the Marriott Bold (Chase) in combination with an Amex (Plat, Gold or Green)?

The Marriott Bold has no annual fee, and if you're Silver, it's 13/14x Bonvoy points per dollar spent at Marriott.

I'm essentially deconstructing the Amex Platinum into a couple of cards with what I need/use rather than what Amex packages up, but I favour Amex points (Membership Rewards).
My hotel spending is mainly with Hilton (and I put that on an Amex Hilton), and I always feel I'm leaving something on the table (points-wise) the few times a year I stay at a Marriott (usually an expensive one).
