IMO what matters most is Bootstrap was used well. They took the purpose of Bootstrap (CSS/HTML Framework and well designed common elements) and then used that alongside their own understanding of how their site should be fit for the purpose.

So many people take Bootstrap as an excuse to not give a single thought to the usability of their site. It's a shame really, Bootstrap is a great tool but inevitably the people that rely on it are relying on it because they have no clue, so they butcher it.
