There are some cool features to the new Prestige card for sure but, for me at least, the earning ability (even at 5x for food and air travel) isn't even close to the Reserve.
I regulary get 2cpp and lots of times higher than that for UR. Its so easy to get 2cpp (again, this is based on my personal travel habits) that I usually make that my cut off point before I decide just to pay cash and save the points. In addition to this is the ease of using those points and finding award availability. The majority of my point transfers are to Hyatt with an occasional Southwest transfer.
I have 2 small kids and don't fly much, and when we do it is usually on Southwest and always on points.
If you fly regularly, especially internationally, I'm sure there is some good value to be had from 5x air travel and dining and some pretty cool award redemptions, but it would be a BIG stretch to say the Prestige is a better card.
PS Don't forget how easy it is to earn UR from Freedom 5%, Ink bonus categories (some also 5%) and Unlimited that can all be transfered into your UR stash as well leading to much quicker earning potential.
