[Orgmode] Add-hook or org-defkey?

[Nathan Neff]

I've seen both of these methods used to define/re-define keys
in org-agenda mode:

--------------- hook-way -------------------------
(add-hook 'org-agenda-mode-hook
             '(lambda ()
                (define-key org-agenda-mode-map "w" 'org-agenda-refile)
))

--------------- another way ----------------

(org-defkey org-agenda-mode-map "w" 'org-agenda-refile)

Is there an advantage to using one way versus the other?

Seems like the second way is simpler.

Thanks,
