Bit of an abstract question, but I'm surprised I'm not finding it already:
Now that Dojo has gone all AMD with 1.7, How does it compare to RequireJS, Lab, Head, etc...
Edit: I realize lab and head aren't AMD loaders. To clarify:
I'm liking how Dojo is splitting it's core out into small, concise, single-purpose modules. (I'd assume these module would work with any AMD loader now, though I haven't tested that) This leaves dojo.js itself barely more than an AMD loader.
So the question is: As an AMD loader, how does Dojo stack up. In terms of how well if follows the spec, speed, size, efficiency, whatever. It's the new kid in a very heated topic it seems, but I've heard surprisingly little about it.
