This is my first SUP and while I do not have experience with others for comparison, I am very happy with the Nalu 12.5 so far. It is a hybrid that has hook anchors to attach an optional seat to use as a sit-on-top kayak. My paddle converts from a long-handled oar to use while standing to a twin-bladed paddle for seated use. With a little practice and good balance it is not hard to go from standing to seated and back on the fly.
Pros
Sturdy and stable. Hybrid stand-up or sit down use. Well made.
Cons
Quite heavy to manipulate by oneself, but that may be unavoidable with a long, big board.
Usage
I use the Nalu 12.5 for exercise and recreational paddling on a creek/still river near my home. Have not tried in the surf yet but looking forward to starting out in quieter bay-side waters at the ocean this summer.
