FSP Epsilon or OCZ GameXStream?

Not sure where you got that from, it's the exact same platform, exactly the same power output. OCZ use a different fan and paint job, but aside from that the units are identical.

OCZ have better warranty terms, if that's worth the extra $10 to you, go with that. If not, stick with the Epsilon.

Ah, now I see where you're getting that from, and Bradan you're very close.

FSP originally released the Epsilon 700W certified for 15A on each of the +12V rails. OCZ released their GameXStream 700W claiming 18A on each of the +12V rails.

Assuming I'm recalling all this correctly (it's been a while), OCZ didn't want to appear as if they were overrating the Epsilon platform, so put pressure on FSP to have the unit recertified. FSP did so, and the unit is now certified for 18A on each rail (that it's now certified for 18A on each rail I am certain of). Apparently newegg never updated their photos or specs list, but the new Epsilons have the correct 18A labelling. Whatever they stick on the label, the actual OCP points are 20A.

It's actually not all that unusual for companies to take an OEM design, and exaggerate the labelling, but of course that doesn't change the amount of power the unit can output - the Epsilon and GameXStream are identical internally, regardless of what each company rate it for.

As a side note, this never affected the total +12V amperage rating, which is not the sum of the ratings of the individual rails.
