Best wizard shield?

Stormshield or Lidlesswall?

Tal Rasha is clearly an MF set so that's reserved for other uses.

Stormshield seems better for me.

Much more block, much more amount of damage blocked. Linless also got attack speed which is bad for channeled spells.

I haven't tried inferno yet, but from what people are saying here it may become that both of them are completely useless
