while i cant say any thing about the others that you have mentioned. i can tell ya about the feel free 13 and the sg 130. the feel free 13 is a heavy kayak.and the wheel in the keel is great on hard surfaces but its useless in the sand. as for the sg 130. i have one and its a great kayak. very stable to even where you can even stand and fish from it. and its got plenty of storage. i dont take a create with this kayak. and the best 4 parts of this kayak are. the new upgraded seat, you can fish or just paddle in ether the high or low position and its a very comfortable seat. its comes with a rudder and paddle and best of all the price. and it meets what you are looking for in a kayak
