The 1.5mm Camaro Blacktec is still hard to beat and now they offer one with a dry zipper, no more cold water leaking through the zipper. I do love the 3/4 leg length offered by Stokes but at 1mm they are not as warm as the 1.5mm Camaro. I find the 3/4 length leg (just below the knee) of the Stokes easier to get on and off, has no material to get in the way of your boots compared to full length suit, and you never get water up the legs during starts like you can with the mid thigh length suit. For me the ultimate suit would be 1.5mm smooth skin 3/4 length with a dry zipper.
O'Neill makes good stuff but they don't offer a full smooth skin neoprene suit which is a must, without it you get evaporative cooling making the suit noticeably colder compared to one of the same thickness with smooth skin.
