The part the comparison articles leave out: a card can lose on the numbers and still be the right card because of where its points go. The reach row above shows which named programs each currency actually transfers to; a Perko report lists a card that reaches your program and loses on the numbers as listed, not recommended, with the dollar gap, so the choice is yours with the price attached.

Run both against your own numbers - one minute, free, and the answer is about your spend, not a sample profile.
