Paperback or ebook?
The trade is narrower than it looks. Print is better for writing alongside; the ebook is better for finding things again and for reading unobserved. What decides it for most people is neither — it is where their reading habit already lives.

Where each one wins outright
Six differences, stated without pretending the answer is close in either direction.
| What you want | Which one, and why |
|---|---|
| To write alongside it | Paperback. A notebook and an open book share a table in a way a notebook and a phone do not, and the physical proximity does more than it sounds like it should. |
| To find a passage again | Ebook, decisively. Full-text search plus a highlight list, which after a month is a compact map of what you keep returning to. No print edition can approach this. |
| To read at night | Ebook. Adjustable text, dark mode, no lamp — relevant, since a good deal of this reading happens at 2am. |
| To read unobserved | Ebook. Nobody can read the cover over your shoulder and there is nothing on a shelf. For some readers this is the whole decision. |
| To not lose your place in the material | Paperback. Physical position in a book is a genuine memory aid — you remember roughly where something was on the page, and that does not survive reflowable text. |
| Cheapest | Usually the ebook, though it varies by listing. Worth checking both rather than assuming. |
Four readers, four answers
If the list above did not settle it, one of these usually does.
You will do the written work
Half the chapters end in a prompt. If you know you will answer them, print earns its cost — and if you know you will not, do not pay extra hoping it will make you.
Everything you have finished in two years was on a screen
Whatever you already read on is the format that gets used. A paperback will not be the exception for this book.
You would rather nobody knew what you were reading
A live consideration in a shared house, on a commute, or at work, and print cannot solve it.
You reread and annotate
Marked-up print is rereadable in a way a highlight list is not — the notes sit next to what they refer to rather than in a separate export.
The follow-up questions
Including whether to have both.
Is the text identical?
Yes. Same thirty chapters, same prompts, same wording. Neither is abridged and neither has extra material.
Do the exercises work in the ebook?
Yes. There are no printed answer boxes in any edition — prompts are answered in your own notebook or notes app, so nothing is lost digitally.
Should I get both?
Rarely worth it for these two, since they overlap heavily. The pairing people actually benefit from is audiobook plus print — one pass to hear it, one to work it.
Can I highlight in the ebook and export it?
Highlights collect into a reviewable list, and export depends on the reading app rather than on the book. Worth checking your app if that is the deciding feature.
What about hardcover?
A different question — build quality and permanence rather than page against screen. There is a separate paperback-versus-hardcover comparison on this site.
Which is easier to start?
The ebook, by a small margin — it arrives instantly and requires no decision about where to put it. Starting is most of the battle, and that is not nothing.
