H/LB or MS/GS for WvW?
Firstly, the differences between SPvP and WvW are wildly contrasted.
Warrior is my main and personally, I would use neither.. some have their own ways they play and own builds they use but some patterns seem to stay pretty constant.. a pretty solid setup is PVT with Hammer/Sword-horn.. it also depends on if you run with a large group or if you roam by yourself or in small units. Ask around and find the playstyle you like ;P Test everything possible.
