Amex Marriott Bonvoy Brilliant Card & Business Card offering free Marriott Platinum status & 100,000 points & more

In response to Chase Marriott Bonvoy Boundless Visa's crazily lucrative five free 50K-nights offer, Amex has also brought us very impressive offers for both the Marriott Bonvoy Brilliant Card and the Marriott Bonvoy Business Card:

• For the 2021 calendar year, enjoy free Marriott Platinum Elite status, the second top tier elite status in the Marriott Bonvoy program, normally achieved by staying at least 50 nights per year and offering lounge access/free breakfasts, upgrades to a suite, and other perks. 
• Earn 100,000 points when you spend at least $5,000 within 3 months of new account opening for either card.
• Earn additional 25,000 points upon your first anniversary when you renew your Marriott Bonvoy Brilliant Card.  The annual fee is $450 but after considering the annual $300 Marriott credit becomes $150 effectively.  The card offers a free 50K-night upon each anniversary, which can easily negate the effective annual fee.
• Earn up to $150 in statement credits for select U.S. advertising purchases within the first 6 months with your Marriott Bonvoy Business Card, which carries a $125 annual fee and offers a free 35K-night upon each anniversary.

Considering how lucrative Marriott Platinum status could be, we judge these as the best signup bonuses ever for both cards.  The only concern is obviously your travel plan during this pandemic.
