Same, GTD on a paper planner, because many times I can do planning work but don't feel like staring at a screen.

But regarding OP's question about TODO lists, a TODO list should go nowhere near a GTD system. It should go on "project reference/planning", and maybe slowly be moved to "next actions" as needed. But dropping traditional TODO lists on GTD is a bit of a misunderstanding of the system.
