The latter is better ( for most purposes ). I think the reason was due to the
enhanced predictability of the letter - choice item pair over the number
- choice item pair. However, the number is itself better for some situations,
for instance, when you have two menu choices that start with the same letter.

Gary Perlman studied this question experimentally; I'll look up the paper
and post  a summary ( unless gary chooses to do so first ).
