Ok, so Ive had my GG6 for a year or two now and want to try something new. About this time last year I figure, everyone was raving about the 3d polisher, and I liked the fact that even under heavy pressure, it kept spinning. Now, it seems like EVERYONE serious about detailing is using the rupes. I hadnt even heard of them a year ago. Is there anyone who has used both machines who can give a little feedback as to whats better about one or the other? Either will be a step up from my GG6 I assume, which is a great machine, but I think its slower overall than the 2 others I mentioned.
