Pagination on screen sucks, but is sometimes better than badly implemented scrolling. This being said, scrolling should be the default option, because it's much more natural and usable on screen. One should only fallback for pagination for very big content masses (long historical archive etc) and still keep the page size big enough (scrolling inside page is not bad thing). Good scroll implementation uses lazy-loading content (if needed) and placeholder elements to keep page height always correct (assuming the height is reasonable), so that scrollbar works as intented as visual indicator about position. So called "infinite scrolling" where you have to first scroll to end, then wait for spinner for more content, is typically bad ux.
