What the general feeling here RE Marriott Bonvoy Brilliant (esp. vs Platinum)?

Considering canceling my Platinum after this year, as there are just too many credits I don't use considering the new AF. I travel a lot for work; and my expenses are always either reimbursed or paid as per diem. So really the only Platinum perks we genuinely use are Walmart and digital credit … plus lounges when I'm traveling. But the Centurion lounges are overcrowded and watered down these days, so I figured the Priority Pass with Bonvoy would be good enough.

Anyone here using the Marriott as their primary travel/work card? I'd be doing that myself, then putting all my personal spend on my RH Gold.

Thanks!
