I just tried to give Moon+ another go last night, and spent considerable time dithering with the settings, but still went back to Aldiko. I was able to get rid of the cut-off line at the bottom with the "Full line at bottom" setting, and get the page laid out like a book rather than a web page (what's "intelligent" about making every paragraph a blurb?), but a couple of things that still bothered me were the fonts and the brightness stepping. All of the included fonts had a similarly harsh look to me. I don't know what Aldiko's "default" font actually is, but it's a lot easier to look at. As for the brightness, in Moon+ it kind of jumps from one level to another rather than scrolling smoothly as in Aldiko.
Moon+ also takes longer to load a book, and importing books doesn't seem to do anything--it will give me a pop-up list of all the books I just imported, but after I close the pop-up, they're not in my library.
