Hey, guys, just got approved for SPG, I'd love to travel to Europe this summer, so I really appreciated your guys help! This forum really offer tons of great info. 
I now have green and SPG, but I only want to keep one open after one year. I think SPG is a better choice, since AF is lower and the SPG can transfer to airlines 1:1.25(with 20k increment), which is better than MR points. I know SPG points are hard to get unless to stay at SPG properties, but I think compared to Green, SPG is a better point card. Is there any reason that I should keep the Green?

Depending on your spending, IF you want to keep an MR card, the PRG is probably the better choice, as it has much more earning potential, but you would have to assess that against the increased AF. Similarly for SPG vs MR: the points are more valuable but much harder to earn. Do you spend a lot in categories where you could get multiple MR, and would that offset the 25% transfer advantage of SPG.
And, most critically, are the partners you use available in MR vs SPG?
