Lodash has many features that underscore does not have. Also, I am told that Lodash has been implemented in such a way that functions are largely independent of each other so that you can build a custom lodash package that only includes the subset that you use.

It's not a macro framework like jQuery... the kitchen sink isn't in there... though, I do think that probably the string templating could/should become a sub-module... the rest belong together more.
