I have to give Mantano an edge.
I, too, thought that Moon+ was going to be my everyday app, but I had problems with page turns (especially at chapter boundaries). It just wasn't smooth enough. I have jumped around among Moon+, Mantano, Aldiko, Google Play Books, and the Kindle app, but none of them did it all.
For me, the gold standard is Marvin on the iPad. It is just about perfect for me. I have an iPad 3, so the only "problem" with it is the device size. I don't want to buy or switch to an iPad mini right now, but the pull of Marvin is so strong for me that I've switched back to doing my reading on the big iPad.
