On the image with the normal figure and clone Obi, i'd even say the paint on the Normal figure's head looks better!
Thanks puay.
I feel paint work for Clone Obi is more refined (which I now agree with MaulFan), if there is any reason that I would prefer Episode II Obi, its the paint work for this figure which is closer to the rest in the line. I know this might not go well with many collectors here.
