Feedbooks: smaller selection of public domain works but artistic e-book covers (in contrast to Gutenberg's lack of covers for older books). Its perfect if you have a Kindle Fire and love scrolling through your covers on the carousel.
Manybooks: imports books from Gutenberg and other source and adds a cover. Some covers are artistic, others are simple cover templates. Every book gets sorted into categories when uploaded, so the categories on Manybooks is so much more useful than Gutenberg's wiki-ish categories pages.
