I would not make a qualitative statement like that. It is misleading if there are no details. For example, the Antec Signature series units would sit on top of anything that is in the market today. Certainly right up there with Zippy. CWT built Corsair units are pretty good too. Very hard to pick between the Seasonic built units and the CWT built ones. As for Enermax they seem to test very well, but going by past record, reliability is a bit suspect. However, the Modulo82+ series does seem very good.
