What you have to really compare is how much spend you had to make to get the redemption you want. For example. If you need 10,000 MR to book a flight via AMEX Travel and it takes $2500 in spend to get those 10,000 MR, but you only need 6000 UR to book that same flight with Chase but it took you $3000 to get those 6,000 points, then AMEX comes out ahead.
That said, the best value for MR is almost always via transferring to a partner airline and booking via airline rewards. Of course flexibility great decreases when you go that route.
