PHT best overall. PH, from my opinion, a more durable version of PH, but not much difference. Duralast is not meant to be used by anyone on earth. Duralast Tour though, that might be worth taking about when or if that ever hits TW.
Duralast is the stiffest of the bunch, and the deadest. PH is the softest of the three. And PHT is somewhere in between. Further, I'd say PHT is notably "zippier" than Duralast, as Duralast has very low elasticity and PHT has more. Basically, PHT is a stiffer and snappier version of PH. Many feel that PHT has more power than PH, though, due to resilience.
The Duralast on TW is not the same as Nadal uses. He is using Duralast tour. What is on TW is pretty much just balistic polymono repackaged.
To the OP Duralast tour is the stiffest and has the most spin and least power of the bunch. However it is simply terrible in terms of tension maint. It becomes pretty unplayable after about an hour of hitting.
