@extremis: his work is already 'legendary'? Hyperbole much?
Jae Lee wins, he's been at it for a long time and even though his work has been lazy in the later years he is versatile. I have some of the Trasformers/GIJoe books he did a long time ago and they were really good. And his covers are always eye catching.
Ribic by a mile.
Jae Lee's good, but his style is an acquired taste, and I can't read too much of it.
Ribic's work, especially when paired with colorist Dean White, is superb. I haven't read his GoT stuff, but his Ultimates pencils are incredible. Sleek, futuristic no-frills aesthetic, it feels very European and set a new look for the Ultimates relaunch.
