I dunno on TY Points to UR Points. I think Chase is good for Hyatt and if you want to redeem for 1.5x. Having said that, UA has devalued its chart, Chase lost Korean as a partner, and does not have the number of partners that Citi does. For me, Etihad and CX are pretty strong in this respect if you know how to maximize the rules on them. Avianca is another good one for *A. If the redemption is just straight points for miles or for Hyatt, then good argument for Chase. I tend to fly a good bit of OW being an AA EP, so TYP (and Amex MR) I prefer. While I know Chase has Avios (as does Amex MR), I don't generally redeem for domestic economy.

All in all, i find Citi TYP and Amex MR points a little more valuable if you are willing to put in the work and have flexibility of travel and are interested in the aspirational redemptions and/or OW. Certainly, YMMV
