I own a Carbon Mako 6, and have tried a Legend in a choppy tidal current.
I really like the Mako 6. It was the only boat I could find that fit my backside. I find it stable, fast, and fun in swell.
The legend also seemed to fit me well. The seat is different, I felt less slouched, and the knee bump appeared lower, or maybe the seat higher. Anyway it was comfortable and seemed to put me in an efficient position.
It seems to have less volume than the Mako 6, for me, a lightweight this was good.
In swell it was stable and picked up the runs nicely. It tracks better than the Mako 6, but doesn't turn as well (smaller rudder).
I hunted around for challenging water and couldn't find any fault with the Legend. However, that's pretty much the way I feel about the Mako 6.
If I was looking for a new boat, I would test them in a time trial. For me they are both stable, fun, and capable in rough water.
I think it was a glass boat I used, but it didn't feel heavy. I would get a light one because I'm a wimp carrying these things around.
