Kingston or Twinmos?!

What should i choose?

Kingston HyperX DDR 512Mb 370MHz

Or

TwinMos-Winbond DDR 512 400Mhs
???

Which of these two is more overclockble, Faster???

I've heard only great things about the Twinmos-Winbond. And as much reading as I do on this forum, I can't see much on the Kingston, not saying it's not good, but do a little more research on them. Check the sigs of some members with the Kingston and PM them, that's what I do. I am going to order 2x256MB of the Twinmos when my girlfriend stops complaining I spend too much money and time on the rig

i got 2x256 twinmos with windbond, abit nf7 and a Tbred 1800+. Im now running stable @9x200 with timings 5-2-2-2. I can also run at 4-2-2-2 but no performance increase there!! I 've pushed them so far at 210 with 5-2-2-2 but i need some more vcore to run stable!!
