I've switched to native GIMP (the quartz theme isn't ready yet but that's OK for now I edited my own custom theme) and I'm never going back to the X11 version. For one thing the mouse works better in the native version.... particularly the scroll ball on my mighty mouse. The version I'm using has only one dock icon and that's a nice thing. I really like the menubar integration. The app simply acts better for me natively than it did through X11 where it feels more foreign. So lisanet you may not see the value in it but that doesn't mean there isn't any.
