It would seem the design that can survive the most extinctions would be the clear winner in the end.

Cold blood probably makes a lot of sense for an aquatic ambush predator that needs to lie motionless for most of its life. Keeping that body warm the whole time wastes a lot of energy, especially under water. If you conserve energy, you can go longer without food which is important if you are waiting for food to come to you rather than seeking it out.
