theyre all in same price range, i just want to know which one would be better for my pc. now planning on o/c a lot since theyre fast already.

Answer 1

Honestly it's less about the vendor(GSkill, OCZ, Corsair, Buffalo, etc) and more about the manufacture of the IC itself. 
DDR2 has had the original Micron fatbodies, some Elpida chips, and then the more common Micron D9 as the high end RAM to own.  When you research RAM this is just as important to keep in mind as manufacture/warranty/reputation. 
Case in point, while remote it is possible that if you bought a set of the OCZ, the Crucials, and the Corsair all metioned by everyone they could possibly all be Micron D9GMH chips under the hood, all from the same lot of wafers in the fab.  Then it doesn't really matter what manufacture you buy from the will probably clock/overclock about the same, and perform about the same if it's a quality vendor.
If you aren't overclocking I say get the cheapest that meet you specs. (just say 5-5-5 at 500Mhz) .  Of course if you are wanting serious overclock it is necessary to follow some forums and look for vendors binning a good batch of IC's that have been yielding well and buy at the time.  While not common a vendor can have a good batch get great reviews and you buy 4 months later and it's get different IC or a different binning proceedure and not get what you are thinking.
