There are enough users on the web who use older browsers, I'm pretty sure that most of us (web developers) know someone -personally- who uses an older browser.
If you care for your users' experience and what your website looks like to "other people", you should probably use em or percent.
By using em, you make it possible to change sizes "recursively" (and therefor saves you time) by simply changing its parent's font-size.
It may not be your highest priority (such as making progress instead of fixing things) but why not keeping it in mind when developing new sections/features/websites?

You can calculate your own table:
The base size is 16px;
so at 77%, you are setting the base size at: 16px * .77% = 12.32 px.
10px = 10px/12.32px = .812 em;
11px = 11px/12.32px = .893em;
20px = 20px / 12.32px = 1.54em;
Personally I just use px. ?Every modern browser does something
sensible when zooming with both px and em, so the accessibly argument
is pretty dumb these days. ?The reality is that we are most often
sizing text relative to images/icons which are pixel based artwork,
and the font should be specified the same as the artwork, hence px is
better than em.
