When looking at any high-end kit of memory, they're each going to be great. Choosing Corsair, G.SKILL, Geil or any other brand will give you some kick-ass memory that you won't regret purchasing.
I think it'll come down to two kits, G.SKILL's TridentX memory, or Corsair's Dominator kit. You can get the G.SKILL TridentX 32GB kit at 2400MHz, which I think is the best option, especially if you want it to have some overclocking headroom.
Alternatively, you can look at something like Corsair's Dominator kit, which comes in 1600MHz.
G.SKILL's TridentX memory is probably the way to go, and you can score this from Newegg's website for $309.99.
