Depends on the models. Check this out:
The ones you picked out use Powerchip chips. AKA no-name brand. You want Micron D9s if possible. You can see the Dominator Corsair lineups use them, but the standard ones don't. Now look at for example Crucial. Pretty much ALL their memory uses Micron D9 chips.
Obviously, you're going to pay a price premium for that though, and unless you're an overclocker it's hard to justify.
