I have the 3000s which are nice. Never used rubinos so I can't compare, but I have held both in my hand and the contis seem better put together and they have a kevlar belt and what seems like thicker rubber. I think they look better, but its up for debate whether they are worth the price or not... I'd probably just go with the rubinos if you are happy with them as you'll feel guilty skidding on Conti GP tires.
