Cards: http://semantic-ui.com/views/card.html http://semantic-ui.com/views/card.html vs. http://v4-alpha.getbootstrap.com/components/card/ http://v4-alpha.getbootstrap.com/components/card/ SUI is more compact, aligned and feature rich. Modals: http://semantic-ui.com/modules/modal.html http://semantic-ui.com/modules/modal.html vs. http://getbootstrap.com/javascript/#modals http://getbootstrap.com/javascript/#modals Again, here my vote goes for SUI, it's cleaner and better designed. Untreated Bootstrap is so widely used that without extra styling it looks just another UI with no personality. Design is a sensitive, subjective topic however. Sometimes you want that crude industrial look that Bootstrap has :)
