Bootstrap has better structure then most other UI frameworks, but is built around the fact that you will eventually change the css and images to create your own style. Some of bootstraps styles are pretty limited and bland.

Then there is materializecss that visually is more appealing then bootstap. The color palet alone is enough to consider it, especially if you want to build a flat minimal site. It's also ready to be your full UI experience, but lacks the amount of javascript plug-ins that bootstrap and it's community have built for it(i.e. carousels, popups and some other goodies).

I've never used getskeleton, but its also not necessarily the end all UI solution and is considered a starting point.

Here is a vlog site I built with ROR and materializecss to give you an idea.
