Both the Camaro and sky are awesome cars and I have the great fortune of owning both. Hands down the sky will gather twice the attention, trust me I drive them both regularly. The SS feels more powerful, but the sky feels lighter and much more agile. This is what they were designed for. Both designed by the same company, so busting on Saturn as a brand is ignorant.
We all love our cars, no reason to be so jealous of others, it makes you look bad. After 2 years with the Camaro and 4 with the sky, I would sell the Camaro way before I sell the sky. It is much rarer, unique, more fun, and extremely collectible. This is of course my opinion, but it comes from ownership experience not from hypothetical chatter.
PS - I would not trade either for a mustang or challenger
