 RecommendedPros: 

Custom "search engines". Most Chrome extensions "just work". Available for Windows, Mac, and Linux. Awesome tab features, like Grouping.

Cons: 

Some sites fail to load (rare). OOTB UI could use a bit more polish.

It's a great browser headed in a great direction. Its compatibility with Chrome extensions is a big plus. Extensive set of options allow you to customize at a detailed level, but they don't get in your way if you don't care about that. Last, the browsing history features are amazing.
