Fact is, they're all good:
Mushkin, Patriot, Kingston, Ocz, Corsair, GSkill, Pqi, Crucial, Twinmos. You wont notice a big difference unless you overclock the ram.
Plus look at the specs on those 2 you listed and the Mushkins perform better than the Corsair. I'd listen to Apokalipse, theres a reason he has 6300 posts.
