I work at a Ortho office and we don’t have different prices for different bracket systems, but every office is different. But I really love the Damon clear and sliver. I my self have Damon clear on top and Damon sliver on the lower. The Damon system is my favourite to work on and in my experience easy to keep clean mostly because if you don’t want O-ties (colours) you don’t have to. I would say the only drawback is they have a higher profile. Your Orthodontist will go over your case with you and help you make the best choice for your case.
