I don't have experience from either board but my two cents is that the Ride Machete is a VERY good board. Not sure it will be very playful though. I almost bought myself a Mod Rocker last year and all the research I read on it seemed really positive. I was about to buy it, but was a little late on the great deal going on so I picked out the much cheaper K2 Parkstar instead, which I love!
K2 Jibsaw I have been looking at as well. Kind of hooked on the flat with rockered tips, seems like a profile I would like, just looking for which one.
