I used to use Moon reader, but now I tend to just upload my drm free books to google play and use the play book reader. It syncs, it reads to you (with ivona voice amy, it's tolerable) and it stays in your cloud library. And it has the smoothest 3d page turn animation. I usually end up buying a Kindle ebook, use calibre plug in to dedrm in windows then convert to epub then either upload to google play on the pc, or upload it later when accessing my calibre library with the calibre companion app.
