I own kits for various clubs and teams from Diadora, Nike, Adidas and Macron; I've never noticed a true material difference between them, only fit. There's only so many ways to spin plastic. I prefer Nike's cut of kits more than any other manufacturer, but I don't see/feel a real difference between Adidas' ClimaCool/ClimaLite and Macron's products in regards to cut or material. The Diadora I have is pretty old and a GK kit, so I don't include it in the discussion.
You can dislike Macron for the over branding and the cut (which is really where you see a difference in kits), but to say "oh it's rubbish material" is just whinging for whinging's sake.
That's probably my main gripe with them, the cut and the way it fits to the body. The material definitely feels a lot different than the Nike kits we had though, to me at least.
