My 15 was a 16gb, 256. I configured the 13 with 24gb, 256. I never thought I would notice any difference in response times, especially considering that the ssd speeds are identical but it's probably the m4 chip and the difference in memory bandwidth. This thing is a speed demon!
I travel a lot so the dimensions are also much better for me. Basically I'm a happy camper.
