I think there's only one ceramic tint. Huper.
Basically, metallic is nice cuz it rejects heat more than non-metallic films. Downside is they affect reception from radio/cell phones/radar detectors/etc. Plus, they have that weird shimmery look.
Ceramic was developed to basically surpass the performance of metallic tint, yet without any of the disadvantages. It's main problem is cost. Stuff is expensive.
