I had a great time talking at April 22, 2014 Cascade Bos meetup. My talk was titled: Embedded web fonts, Icon fonts and SVG – Vector-based Responsive Web Design using CSS.
Coincidentally, the same day, Chris Coyer of CSS-Tricks have published a blog post titled: Inline SVG vs Icon Fonts [CAGEMATCH].
His conclusion is very similar to my conclusion but better!
If you can go IE 9+ / Android 3+, inline SVG is better at pretty much everything than icon fonts. If you need the deeper browser support, I feel like an inline SVG fallback would be too big of a pain to be worth it.
Definitely worth a read if you are interested in this topic.
