The Kink comes in 2 sizes (153 & 155) whereas the Skate Banana has 5 sizes (148, 151, 152, 156 and 159). The Kink has a middle flex whereas the Banana has a softer to stiffer flex depending on what size you're riding. It gets stiffer as it get's bigger. That sounds gross. Anyways. The Kink is wider all around. So get what fits your feet. Hope this helps.
