I have only tried it once for a very short amount of time, so I don't really have an opinion about it specifically I'm afraid!
There's one thing I can say more generally though: I like how many frontend frameworks, libraries and methodologies are converging around this shared model of "components".
The old model of thinking about websites as "documents" doesn't work for the complex applications we're now building on the web. Components are a much better model for building user interfaces.
