Of course, it depends on your travel and spending habits. For me, AmEx MR allows me to transfer points to foreign airlines whose redemption rates are much better than U.S. airlines. For instance, I booked a pair of business class seats on an AF flight instead of a DL flight to Europe next month. I booked months ago. For the same destination, I saved thousands of dollars worth of points redeeming through AF instead of DL. But there's several variables listed in that simple example. so my experience may not apply to you.
