With "big" comes large inertia, meaning it takes long to recognize the need
for and implement change.

Basically, em and % WRT text size are identical twins. Both are just certain
ways to write decimal mixed numbers. 110/100, 1.1em & 110% are all identical
numbers. 1/2, .5em & 50% are all identical numbers. 300/100, 3em & 100% are
all identical numbers.
The main difference between em and % has to do with their application to
sizes other than text, and is not related to your immediate puzzlement.
There is one difference between em and % WRT text size that one who writes
CSS that will be used by older IE versions needs to know, but it is a bug
that is explained on
http://css-discuss.incutio.com/?page=InternetExplorerWinBugs along with an
% is often best when you need to size WRT an object other than text, like a
viewport or an image. Em usually works best when you need to size WRT text
size, which just happens to be an excellent base of reference if you wish
high usability, high accessibility and/or resolution independence.

It's not so bad when you keep it simple as possible, and stop finding
non-existent differences. ;-)
