Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

Kobo

The overall ebook and audiobook catalogue, especially exclusive or first-run titles, is smaller than Amazon can offer through Kindle and Audible.
Kobo Plus, the unlimited subscription layer, is not available in every country the hardware and store otherwise serve.
Hardware pricing for higher-end note-taking models runs into the several-hundred-dollar range, which is a real commitment against reading on a phone for free.
Software updates and app polish have historically lagged the Kindle app in some regions, particularly around syncing and highlighting features.
This is a distinct product from Kobo Writing Life, and readers looking for author or publishing tools need that separate platform, not this one.
