Hmmm... after very quickly looking at Globalize, I'd say there are two things about formatjs.io that I see as main differences:
* Integrations with Handlebars, Dust, and React hopefully make formatjs.io easy to use (since people are already using one of these).
* Focus on the ICU message format, which is fairly simple yet fairly expressive. (Professional translators should hopefully be familiar with this syntax, and it's actually fairly straightforward for us engineers to use.)
One thing that looks interesting (to me) about Globalize is the way the latest/freshest CLDR data is loaded.
