In regards to actual brand names, most high performance modules are the same. Only differences matter when really overclocking the modules.
Go for the best price for timings and speed. IMO, read reviews on Newegg or something to see the reliability of the RAM in question. (I've had a friend who bought some Corsair RAM; most ratings on Newegg complained of defective modules, and what do you know, my friend's modules failed on him...)
