I almost bought the rainbow last week. I like small bumps like that and it looks so pretty and fun! I hate the other one's look. Something about the floral glass pieces really turn me off and look so tacky to me. No idea why?
amber wave is prettier in my opinion. I think the biggest factor for me is that the rainbow G has so many nubbs. I've had some issues with texture before. I would try it again, but the smooth wavy-ness would work better with my anatomy
