Having used both only a small amount, here is my opinion: Jefe.
The Dagger outfitting is super cheap these past few years, and as a result is both leaky and less comfortable. They use only 2 screws to mount the sides of the seat, and the system they have developed leaks terribly b/c they can't stay tight. In contrast, the Jefe is like sitting in a comfy chair, doesn't leak, and lasts longer.
As far as general characteristics, the Jefe is a boat that loves to spin. Lots of sculling strokes, open faced and closed faced draw strokes, etc. Since it seems to not need as much carving, I find it easier to control very quickly in a pinch.
I also like the Jackson Rocker. Requires more carving than the Jefe, has an amazing secondary stability, autoboof, doesn't backflip you hitting huge waves head on, etc. I like the engineering of the outfitting being so freakin simple (an also doesn't leak- no screw holes through the shell), but apparently the Jefe outfitting will last longer and is definitely more comfortable. The Jackson uses the nicer plastic (bi-lateral matrix or whatnot). The downside to the Jackson plastic is if one puts a hole in the boat it is not patchable (via blowtorch). Lighter boat.
