I always liked CSS for giving us the flexibility to use more than just
the standard 7 HTML font sizes, but if you use keywords, you're sticking
yourself with those 7 sizes again. But this may not be important to you
-- most sites really don't use or need a whole range of fine font size
differences. But that's one pro to using ems or percentages.
Another pro -- they are relative to the user's font size. If a user has
their default font set to large, and then you go and set everything to
small as a base font, you are overriding their preferences right off the
bat.
The css-d wiki probably has even more information about the pros and
cons of each approach -- it's a continual debate.
As I said before, if you do use ems or percentages you would be wise to
set a percentage font size in the body to avoid IE font size inheritance
issues.
