The Jefe is an awesome creek boat. It turns well, autoboofs, surfaces great, punches holes great, rolls easily, and is very sturdy.
The Nomad is also an awesome creeker. I thought that it tracked better than the Jefe. It turns, boofs, surfaces, rolls, and punches holes just as well as the Jefe. It is a little shorter and a little lighter than the Jefe (maybe an advantage, maybe not, depending on what you want). And the Nomad is the strongest boat on the market. The biggest downside to the Nomad is how difficult it is getting stuff in the back, which they are fixing in next year's model.
The Pyranha Burn is also one of my favorite modern creek boats. Unlike the Jefe and Nomad, it has edges and a flat hull. This makes for an easier transition from playboats and can be a benefit in big water IV and V, though it is a disadvantage in low-volume steep creeking. It does everything just as well as the Nomad and Jefe, in my opinion. My biggest issue was that it does not feel quite as bomber as the others.
All three are awesome creekers. Best of luck.
