I have to say, the new Green is looking like a solid card with 3x travel and dining – the same earning structure in MR as the CSR earns in UR – with "only" a $150 AF. By comparison, the CSP, which earns 2x UR in the same categories carries a $95 AF. The Green also comes with $300 in credits without the CSR's $450 AF, but these credits are highly specific unlike the CSR's general travel credits and seems intended to get you to spend money on things you might not have planned.
CLEAR is nice and generally considered faster than TSA PreCheck and Global Entry, but its availability is limited to fewer airports and it costs $179 per year; adding up to 3 family members will cost another $50 each (
discounted for Delta SkyMiles members and cardholders). Away luggage is nice, but carry-ons start at $225 (Away does often send out coupons for $20 off). LoungeBuddy could be useful if you find yourself in an airport terminal without a Priority Pass, Centurion, or Escape Lounge, but other cards seem to have this space well covered, and LoungeBuddy doesn't have participating lounges everywhere to fill in the gaps.
As already being discussed on reddit, the Green's 3x MR travel and dining bonus categories could eat into the more expensive Gold ($250 AF) and Platinum ($550 AF) in signups and retention, or at least spend. 3x MR at restaurants on the Green is almost as good as the Gold's 4x MR; and the 3x MR on travel is broader and arguably more useful than the Gold's 3x MR and the Platinum's 5x MR on flights and Amex Travel.
Amex is still lacking a card that gives redemption of MR points through their travel portal a bonus like the CIP, CSP or CSR does for UR. The Biz Plat with a $595 AF offers a 35% rebate of points for certain kinds of award tickets on your selected airline for an effective 1.54 cpp redemption, but it's not instant or as useable as a 1.25 or 1.5 cpp redemption on the Chase cards. The Schwab Plat offers a 1.25 cpp cash out option, but it requires you to sign up for a brokerage account, another personal card, and a $550 AF. As
@calypso726 pointed out, those fees really add up.
** For anyone considering signing up for this card, you won't be eligible for the SUB if you have or previously had the Amex Green card before the refresh. Also, it is a personal charge card that will add to your 5/24 count with Chase, but it does not count against the 5 Amex credit card limit.
