While some of the above programs offer saving to PDF, only getxbook offers the ability to save a book as DejaVu, or automatically OCR the pages to extract the text in them, saving it either into a text file, or embedded in a PDF or DejaVu file. It requires you to download one page at a time, and hence it makes the process of downloading a book very time and labour consuming. It goes without saying therefore that it has a rather significant dependency. Google Book Downloader UserScript is a GreaseMonkey script, which runs in Firefox. It also depends on Python and GTK, which are rather slow, large, and heavy. It's much larger and more complex (and hence likely more buggy), and less mature.

PySheng is a free Python program and runs on free platforms. It can convert the book pages directly into one PDF. It is also not clear whether 'preview only' availability books can be downloaded. Google Book Downloader is Windows only, and depends on lots of proprietary software to run. Given that a major goal of getxbook is ensuring the freedom to read, I am disqualifying these from any comparison. By forbidding the free reading, sharing and modification of their code, they deprive their users of important freedoms, and likely also spy on their reading habits.
