I'm a fan of both. I find the green super stainless (the Russian greens) are extremely smooth and fairly sharp but only last me 3 shaves or so. The Yellow sharpedge are sharper, but admitedly are slightly rough on first shave... they do get smoother after that and they seem to last longer, usually 5 shaves for me.
Everyone differs but the answer seems simple to me, get rid of your yellows and stick with greens. Must admit, I prefer the green though I think we're probably in a minority.
I've been using the Yellows (two boxes from Russia courtesy of shaving-shack.com), they're a little aggressive on days one and two, but days three are a lot softer (on day one I use side A and on day two I use side B, three and four use A and B respectively). Each day has two passes, first WTG and second XTG. By day five though the blades just don't have a sufficiently sharp enough cutting edge to complete the job with any success.
They're very comparable to Derby blades, but on days three and four they're just a little more forgiving. Not bad at all.
A little interesting how on the box the blades are using the USA trademark. Their contents is made in Russia, but if you wish to write to Gillette then you can use their UAE address. Strange world how it's all segmented to totally different places.
