Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Atticus
- It is a browser application, so manuscripts depend on local browser storage and cloud sync, and a sync failure or cleared browser data is a more serious event than a corrupted file in a native application.
- Long manuscripts and image-heavy books slow the editor noticeably, which is felt most by exactly the non-fiction authors who need figures and tables.
- Typographic control is limited to the supplied themes and their options, so fine control over kerning, hyphenation, running heads and unusual page structures is unavailable.
- Several features announced at launch arrived slowly, so buyers should judge it on what it does today rather than on the published roadmap.
- It produces files and nothing else, with no distribution, ISBN or retailer relationship, so it solves one step of publishing and none of the commercial ones.
Calibre
- The interface is dense and widely described as unintuitive, with a great deal exposed at once
- Conversion between formats is imperfect, and complex layouts degrade
- Cannot remove DRM, so purchased books from most stores will not convert without third-party plugins
- Heavy for someone who only wants to read rather than manage a library

Answered from the vendors’ own pages
Atticus: Is the price really one payment?
Yes. One hundred and forty-seven dollars once, with updates included, rather than an annual renewal. Confirm the current figure before buying, as prices change.
Calibre: Is Calibre free?
Yes, open source under the GPL.
Atticus: Does it work offline?
It caches for offline working once loaded, but it is fundamentally a web application. If you want a native desktop program that never touches a browser, this is not it.
Calibre: Can Calibre convert DRM-protected books?
No. It does not remove DRM, so most store-purchased books cannot be converted with Calibre alone.
Atticus: Can it replace InDesign?
For standard prose, yes and more cheaply. For illustrated books, textbooks, cookbooks or anything with a designed page, no.
Calibre: Does it work with Kindle?
Yes, it transfers to Kindle and most other e-readers and converts to the formats they use.
