Custom -- most of the code generation I've done has been about binding Go functionality into UI markup languages (similar to the way ActionScript binding in Flex works, for those who have used that) as opposed to generics-like functionality. I've never used gen, it looks pretty nice though, at least based on the linked docs and it is probably a good answer to Pxtl's question about publicly available examples.
