sudo apt-get install qpdfview) is the best alternative as lightweight tabbed PDF viewer.
Editing: not available. Same for annotating. If you need these, you need another alternative.
Viewing options: all usual viewing options are there, including zooming, fitting to page, continuous and non-continuous scrolling, full-screen and rotating pages.
Usability: it's not beautiful, but works fine. Almost everything is under single-level menus instead of long toolbars. There's keyboard shortcuts for every menu item, so no need to click with mouse for regularly used things (for example, switching between tabs and rotating pages on broken PDFs)
Compatibility: I haven't encountered PDF file that wasn't rendered properly by qpdfview. This includes relatively complex scientific articles and PDFs with graphics. qpdfview also supports postscript and DjVU with plugins (installed by default).
Bugs: the only bug I have encountered is that search does not find scandinavian characters (äöå) properly. It worked well with ASCII charset (plain English).
