Yes, I looked at Evga G2 - but I read that while its components are slightly better quality, it's also louder than RMx. I also checked out Fractal Design Ion+ which is platinium cert, but I read on tomshardware review that it's not that great of psu - its "only" good. And paying more to get 1% better efficiency will pay off maybe after 20 years and won't generate significantly less heat, so I don't see any point investing in it.
All in all, when it comes to price, RMx with discount from that shop is like 30-50$ cheaper than those two.
EDIT: There is also a Corsair HX 750W for 10$ more...
