Well, here's me disagreeing.
The lightning hammerdin is in my view too much of a cooldown machine. Yeah, you pop your cooldowns for elites, but once they're done, your damage drops to a very low level for a long time, as in you'll only basically be throwing Justice and Blessed Hammers. With Bombardment having a 60 second CD and Akarat's Champion 90 seconds, you can't really pop them at any other point than when you finally find a pack of elites. Don't get me wrong, this build definitely facemelts elites for 20 seconds, but then it'll be quite a while before you'll get any burst going again.
I'm sticking with my holy hammerdin;

With Falling Sword, Condemn and Heaven's Fury on short cooldowns, you get to pop bursts almost constantly. You can drop casters and ranged from the back lines with Fury while using Falling Sword to drop a huge crit on a pack elsewhere, then run in the middle of yet another pack and vaporize it with Condemn. With Blade of Prophecy, the Condemn alone in this build will melt elites instantly. Although, I don't have it myself... Yet.
This build also heals very nicely, and there's no combo machine that it's dependent on, so you can switch out one of the damage abilities to something else, and you get to have Steed Charge.
The lightning hammerdin might be a good spec to play if you run random groups, so the rest of the group can carry you from elite pack to the next, where you can pop your load and shine, but as far as solo farming goes, I'm definitely liking the versatility of the holy build a lot, lot more.
