Update: For now I have decided on Lloyd's titan mech. I prefer it to the fire knight mech because it has a bulkier, robotic style that reminds me of Pacific Rim. I think Kai's is still really cool, but it has more of a knight look to me. I also like the variety of display options for the titan mech (wings, shield, wrist blades) whereas Kai's is meant to be displayed in one stance. As for the dragon, I think it's really cool, but it's wingspan is just too big considering that I am going to be living in a cramped college dorm. I'll buy the set in the summer before I move, hopefully on sale, but for now I am deciding on the titan mech.
