I don't have a G2, but my Manitou fork falls somewhere in between standard offset and G2 which I thought was a perfect "best of both" scenario.. So far, nothing really negative to speak of. Handles great.
I honestly doubt you'll encounter any problems regardless of which offset fork you go with, but it's certainly worth looking into imo. Besides the price, the non-standard off set of the Manitou fork was one of the reasons I settled on it.
I think most Manitous are this way but I'm basing this entirely on memory, so I apologize if I'm mistaken.
