 Riot 2.0 provides a similar component-based development model (which is called a "tag" in Riot), with a minimal and beautifully designed API. Riot and Vue probably share a lot in design philosophies. However, despite being a bit heavier than Riot, Vue does offer some significant advantages:
 
-- True conditional rendering. Riot renders all if branches and simply shows/hides them.
+- [Transition effect system](transitions.html). Riot has none.
 - A far more powerful router. Riot’s routing API is extremely minimal.
+- Better performance. Riot [traverses a DOM tree](http://riotjs.com/compare/#virtual-dom-vs-expressions-binding) rather than using a virtual DOM, so suffers from the same performance issues as Angular 1.
 - More mature tooling support. Vue provides official support for [Webpack](https://github.com/vuejs/vue-loader) and [Browserify](https://github.com/vuejs/vueify), while Riot relies on community support for build system integration.
-- [Transition effect system](transitions.html). Riot has none.
-- Better performance. [Despite advertising](https://github.com/vuejs/vuejs.org/issues/346) use of a virtual DOM, Riot in fact uses dirty checking and thus suffers from the same performance issues as Angular 1.
