If I was after a board with higher performance I would pick the Smik due to its pulled in tail which to me means you can keep your back foot planted at centre without having to move it from rail to rail to initiate a hard turn. & the rocker looks a little more than the JP which helps on the steeper drops. And the slimmer width may help for down the line speed.
I have the JP wide body 8ft 2inch. I use it & love it for its stability due to its wider width & flatter deck. Great for those areas where you get messy chop that bounces back from the rocks & breakwalls. Very comfortable board to stand on.
So it all depends what your main use would be.
