I know it's not a bookmarking tool, but It works well. Tags help organizing, there's a 'link' post type that points back to the original, you don't have to accept limited formatting that is the case with Pinboard, Refind, and so on. A handy bookmarklet make capturing a link and selected text reasonably easy. But Tumblr lacks import and export (although third party export tools exist).
