Pros
Pro Built on PostCSS
cssnext is a PostCSS plugin, which makes it pretty easy to use for people who are already using PostCSS.
Pro JavaScript-based
Because the parser/compiler can function in a web browser, it can be used with systems that cannot run similar technology on the server. For example, you could build a WordPress plugin with a front-end application that transforms CSS.
Pro No need to learn a new syntax
Since css-next only adds new CSS features in a way that all browsers can support it, it's still CSS. So there's no need to learn any new syntax.
Cons
Con Lack of support in IDEs
Currently there is very little support for syntax highlighting when writing PostCSS plugins.
