Share the best online bookmark manager?

Let me ease your search, straign away goto http://www.feedbus.com/bookmarks -here is the list of all online bookmark managers. But I'm confused to choose the best among them. Currently I'm using del.icio.us, google bookmark, furl and shadows. But none of them have all the features in one. I need a bookmark manager that has all features. I think google bookmark will prove to be the best when it will be out of beta. Well, for now del.icio.us rocks!!!
