Your size, your comfort level, and the type of fishing you wish to do are all important factors, as well as how you plan to transport the kayak.
I've got a NuCanoe Frontier. Incredible stability, lots of room. You fish and paddle from a jon boat seat, and normal people can stand and fish from it without problems, it tracks very well, can be used solo or tandem, and is very easy to add accessories with a long yakattack style track on both sides. The downsides are that it's heavy (about 90 pounds with seat, 72 lbs without seat), so it's hard to car top, and it's on the slow side (about the same as the Slayer, perhaps a little slower... I get 4.3 MPH on my GPS with normal effort and questionable technique, but I've had it over 6 MPH in sprints). BUT.... I bought it because of my size.... I'm a giant, and it's one of the few kayaks that will support me properly.
One bonus is that it's an easier transition to the NuCanoe from a bass boat.... Similar kinds of seats, standing whenever you wish, etc. Not always easy in most fishing kayaks.
One disadvantage is that kayak "purists" look down on it for being too wide and stable and they presume it doesn't paddle well without ever trying it.
The Slayer may be a great kayak for you. But the NuCanoe is a perfect one for me.
