Got the Chase Marriott card at the end of December, $6k limit, working near the end of that spend requirement for the bonus. As I read more about the value of the points earned, however, The Points Guy thinks the Marriott points are worth about 0.6 to 0.7 tenths of a cent. Not 6 cents, two points to make up one cent.
Hyatt on the other hand is more like 2 cents per point. If you look at the conversion ratio for Diners Club Rewards points, this looks to be the same thing: From 1,000 Diners Club Rewards points you get 1,000 Delta miles, or a lot more Marriott Points, or a lot less Hyatt points, because the Hyatt points are more valuable.
So why not cut to the chase and just get the Hyatt card and earn points that are each worth closer to 2 cents?
I recently set up a Hyatt Gold Passport account, and then got an email recently encouraging me to app for the Hyatt Chase card. Chase and I go way back, from mergers they did I've had like 6 different cards with them. All but two were closed for various reasons as of October 2014.
The first app I did was for the Marriott, in December. Nice approval, $6k, it's a black and steel card, so there is that 
Step two now, I was worried about the Hyatt app. Pulled the trigger this morning, instant approved for $12k. Knocked my socks off. Soon to be one of my go-to cards.
Step three, to be done in late February, is to follow up the postal mailing I got with a promo for the Chase United MileagePlus Explorer card, 50,000 miles bonus. This one also has an expiration date of Feb 28, thus the scheduling out. This was originally going to be my second (and last) chase card for a while.
I know I've added quite a few cards in the last few months, particularly poking the Chase bear three times in a row, but these hotel cards have the annual free night, so they are almost like no AF cards. And I'm presuming the banks look favorably on that AF. Many of the other cards I have, I really like, but I'm working rapidly to pay down balances, taking advantage of low interest BT offers, and once those BT offers are gone, my spend to support 17 cards (after the United card I will have 17 active cards) just is not there, so I'm going to be closing some. Two US Bank cards for sure. If another bank does AA, so be it, but I'm not really worried about them, I don't think there are others who will close accounts because their risk is so low right now.
Anyway, I'm really happy I got the Hyatt out of the way. Like I said, a new go-to card, particularly for dining.
Grats on your Hyatt approval, excellent CL
congrats
Hyatt sounds like a wonderful Chase card to have. Enjoy!
