I have never tried the nucanoe 10
But own the frontier 12 and love it. Super supet stable endless rigging options and multiple seat options. I can stand and fish easily without ever feeling like it will tip. It is not the fastest paddling kayak but that is one thing you sacrifice with the width for the level of stability. If you can manage it I would recommend the 12 ft model regardless which model you choose. You would be surprised how much room your gear can take up. I don't think I could be comfortable in the 10 ft model. I think it would be a bit cramped.
