I loved both of those series, and I think each one did a great job of creating a compelling environment. The supporting characters, the setting - these story elements were just as integral (for me) as anything Bishop brought to the table as the protagonist.
Ishmael Ortega and the many mutants of Mutant Town were so cool, as were the Kith and Nom the Giant from LXM.
