The Chase UR system is pretty good, but I use the AMEX SPG Biz card to rack up 6x Marriott Points and also keep it segregated from my CSR that is used for personal use. Makes expenses much easier.

Also, I don't use UR at all when I am booking hotels, since it comes through as Expedia and you don't get any elite benefits at the hotel because of that. So it's nice to have an easy source of Marriott points for personal hotel bookings without having to transfer from CSR and getting a lower redemption rate because of that.
