I just finally switched one of our projects from a very crappy framework called Metro UI to Bootstrap. The reasons were that the other framework was very poorly coded, supported almost nothing out of the box and also looked pretty bad in a lot of scenarios. Compared to that, Bootstrap works incredibly well, is very well-maintained, supports almost every scenario you can think of (if it isn't supported out of the box, you can find some plugin for it) and adheres to the latest web standards. On top, it's very easy to make something look good with Bootstrap (it will never look GREAT, but solid at least).
