Given a choice to download the following formats, which would you choose and
why?

MPEG-4
WMV (v9)
Real (v10)

An MPEG variant, by all means. The other two are closed, proprietary
formats, and that's just never a good idea when you're trying to appeal
to a wide audience like the web. And as other pointed out, Real is
just *awful* software.
