This is essentially the question posed in post
206.
And to sum the responses up: 1) better "pay with points" value on UR points (1.5 cents per point), 2) better concierge, 3) better hotel perks, and 4) some other largely unpersuasive perks like gift cards.
Beyond those, the card isn't much better than JPM Select. I know nothing about Sapphire card benefits, but I assume they're similar but probably not quite as broad in some respects as JPM Select.
