Can't go wrong with either board in the surf...

But if I was faced with the decision I would probably go the Coreban performer. It will be good in waves to head and abit in height which is good enough for Cott, has much better glide for the long paddles out and in at lano, stability is vastly different (about 20L) so if your average ability you'll appreciate it. The coreban is versatile mainly being a wave board but acceptable and enjoyable in flat water paddling unlike the mano, that is a straight out surf SUP.

I'm sure you'll get some mixed responses, that's just my 2c worth

Have'nt ridden a JL but have surfed the 9-6 Coreban. I'm 88kg and I found the board extermely bouyant/corky , it's really stable and very easy to surf. It's construction it's tough as nails , I put it through hell in PNG on the reef breaks and it came out with only a few scratches.

Here is a shot of the board in action in PNG.
