The Black Friday sales season is coming! These deals are the best available right now, but the coming weeks may bring even better value across a wider range of products.

While working on my review of the Kobo Nia this week, I was reminded again of the importance to an eBook reader of the content available for it. You can have the best hardware in the world, but if the device is only able to download books from a badly curated online store that gets its books later than everywhere else, you're not going to have a good time.

With this in mind, I've put together a few thoughts on the comparative strengths and weaknesses of the two biggest specialist eBook stores around: Amazon's Kindle Store, and the Kobo Store.

In the past, just for context, I've always found the Kobo Store to be an unfortunately great advert for buying a Kindle. Our usual refrain has been that Kobo has almost as many eBooks as Amazon, but lags far behind in the two key areas of human-curated recommendations and algorithmic recommendations tailored to a customer's individual preferences.

But let's see how things compare right now.

Availability of eBooks

Looking on the UK stores for books published in the week I wrote this article, I checked for the following titles:

  • Sir David Attenborough's A Life On Our Planet (available on Kobo and Kindle, both £9.99)
  • Michael Spicer's Secret Political Adviser (on Kobo and Kindle, although Kobo was 85p more at time of writing)
  • Monty Don's My Garden World (Kobo and Kindle; both £9.99)
  • The Meaning of Mariah Carey (Kobo and Kindle; both £9.99)

In other words, both stores get new books at pretty much the same time.

I then checked for a few older offerings: both had multiple affordable e-copies of Bob Southey's Life of Nelson, and of Fielding's Joseph Andrews; classics are a goldmine for eBook readers because they are usually out of copyright.

As if to prove this point, neither store had a digital version of John Dickson Carr's Burning Court from 1937, probably because it sits in that awkward zone of being very old but not quite old enough to automatically fall into the public domain.

Recommendations & Browsing

Satisfied that the two stores are equally matched for volume and availability of eBooks, I had a more casual browse to see how well they each managed to throw books at me that I might like.

Both do a decent job of showcasing new material; interestingly, Kobo goes for an approach of highlighting half a dozen notable inclusions for a large variety of genres/subcategories on its home page.

Meanwhile, Amazon offered just two such lists (Business & Finance, and £1 offers) before dropping into a long vertical bestsellers list, although its genre list is prominent and easily accessible in the lefthand sidebar.

I visited, as I always do, Kobo's short stories section, which in the past has caused my glasses to fog up and my top hat to fall off thanks to its density of cheaply produced romance and borderline soft porn. And again, I came across Jingle Balls, Rogues On My Mind and Sinful Secrets on the genre front page.

All mild stuff, and far be it from me to deny readers the opportunity to "cozy up and be ready for some sexy fun", but it all adds to the sense that these are just the most recent or the most SEO-optimised offerings available, rather than the ones a human being or an effective algorithm has decided are appealing choices for a short-story aficionado.

I did wonder if this was a fair comparison since the Kindle store doesn't actually have a short-story page accessible from the main menu. So I ran a search for that term and found, sure enough, a couple of blue stories mixed in with the search results (notably Playing Hard: A Complete Collection of Hot Erotic Short Stories).

But the rest of the page was more convincingly curated/tailored, with more premium-looking collections of short stories appearing nearer the top and, crucially, a curated widget showing 'Contemporary short story collections to devour' sourced from Goodreads.

That's the sort of thing that's actually useful to readers, rather than auto-generated lists of books that have the words short and story crammed multiple times into their metadata and/or happen to have been published recently.

Verdict

Amazon is still ahead, retaining a clear advantage when offering recommendations to the casual browser. This is partly down to the company's far greater data resources, since it knows more about the average visitor and can offer 'similar' items to ones that have been browsed or bought in the past.

(Amazon's recommendations are often mocked for their sillier habits: suggesting you buy something you already bought or linking to utterly unrelated items. But I think you notice it only when it goes wrong, and ignore the many times it surfaced something that was perfect for you, and you bought it, and then forgot where the recommendation even came from.)

Beyond the mountain of data, however, Amazon simply puts in more work - and has more experience - in creating curated entry points via Goodreads widgets and the like.

When you browse Kobo's lists you can frequently see through to the easily gamed algorithm behind the scenes; with Kindle, it feels more like there's a human trying to help you find what you want. An imperfect human who sometimes get it wrong, but one who is doing their best.

All of this applies, however, only to the casual browser who doesn't know what they want to read. If you know that already - if you read books blogs, or get recommendations from friends, or visit real bookshops and then buy online (which is naughty) - then Kobo's store is Kindle's match. They get largely the same books at largely the same time and largely the same price.

Now you've got a good idea of how good the two stores are, it's time to choose some hardware to read with. Visit our guide to the best eBooks readers chart for detailed advice.
