It's good to see that Bootstrap is progressing so fast. Frankly, some features like cards (or some variations of it) have been in Semantic-UI for a while now. It's a matter of personal preference, but like one of the other commentators have suggested, I've also replaced bootstrap in favor of Semantic-UI last year and never looked back. For me, while developing a web app, it's the ability to come up with faster prototypes and then improve upon the UI at later stages that impresses me the most. Bootstrap was the first one to show me how much you can get done in very less time. But, Semantic-UI is simply miles ahead in this aspect. Semantic-UI is a full-fledged package - THe amount of custom CSS I write in comparison to a bootstrap project is way small say, 70-80% less. That's how good Semantic-UI is for me. However, this new Bootstrap release actually excited me and I can't wait to test run it. Kudos and thanks to the team for this awesome release :)
