It depends where you need this information and what kind of information 
it is.

If it is simple (small), needed by the sitemap, existing sitemap 
components or sitemap components that are general in nature apart from 
the value's source (e.g. request parameters, request attributes &c), go 
for an input module.

If it is complex (large), needed mainly by other (custom) components, go 
  for a component.

If you don't know, implement the InputModule interface and provide 
additional access methods as well :-) It's not really an either or 
situation. Afterall, you need a component to implement the InputModule 
interface. And I hope, that it's really simple to implement to it. It's 
just the standardized access methods that set InputModules apart.
