There isn’t really an objective answer to that question. The best latex type for you depends on what you want. Talalay latex is lighter and springier than Dunlop. It will contour better and be more breathable. On the other hand, Dunlop is denser and more durable than Talalay. It will last longer and offer more support.
Another thing to keep in mind is that only Dunlop latex can snag a GOLS certification. The Talalay process involves steps that preclude the final product from being certified organic under strict GOLS standards. That means Talalay can be certified all-natural/pure under other criteria, but if you want truly organic latex, you have to go for Dunlop.
