On the supplied evidence — Rakuten Kobo's 2025 device documentation and OverDrive's platform support pages — the Kobo Libra Colour at $199.99 is the pick for library readers, because borrowing happens on the device itself. The key qualification: this holds in the U.S. and Canada, where the Libby ecosystem runs, and not in most other countries. Amazon's Kindles have borrowed through Libby since their September 2022 firmware update, but the flow sends you to a phone first.
Every load-bearing number here comes from manufacturer spec sheets and platform documentation dated 2025; prices are U.S. list prices as of mid-2025 and will drift.
Why does library support differ between brands?
Library e-books in the U.S. flow through OverDrive's Libby app, and device makers decide individually whether to build Libby in. Kobo has shipped native OverDrive integration since 2018, per Rakuten's support pages: you borrow from the device's library tab and the book downloads over Wi-Fi. Kindle's route, documented on Amazon's help pages since 2022, is a workaround by design — you borrow in the Libby phone app, choose "Send to Kindle," and the device syncs. Both work; one is fewer steps.
Think of it like a mailbox with a slot on the front versus one around the corner. The analogy breaks down here: both paths deliver the same book with the same loan period, so the cost is convenience, not content.
What about EPUB sideloading?
This is where the brands genuinely split. Kobo, PocketBook, and Onyx Boox devices read EPUB files natively, per each maker's format lists. Kindles gained EPUB support in late 2022 through Amazon's Send to Kindle service, but the file is converted to Amazon's format on arrival, per Amazon's own documentation. If your library system issues books outside Libby, or you buy from stores that sell EPUB, the Kobo family treats those files as first-class.
| Feature | Kobo (Libra Colour) | Kindle (Paperwhite) | PocketBook (Verse Pro) |
|---|---|---|---|
| Library borrowing | Native, on-device | Via Libby app, then sync | Native, on-device |
| EPUB without conversion | Yes | No — converted | Yes |
| U.S. price (2025) | $199.99 | $159.99 | $199.99 |
| DRM limits | Adobe/PDF for some loans | Amazon format only | Adobe/PDF |
Do loans behave the same everywhere?
No, and this is the qualification worth repeating. Libby operates in the U.S., Canada, and a small set of other territories; outside them, native library borrowing on any device is limited to whatever your local system provides. Kindle's library flow is U.S.-only, per Amazon's help page. If you read in Germany or Brazil, the comparison above mostly dissolves and format openness becomes the deciding factor instead.
What the sources did not establish
The spec sheets do not tell you how page-turn latency feels on library loans versus purchases — no independent measurement in the pack covers that, and this site does not fake hands-on impressions. Battery figures are manufacturer claims: six weeks of reading for the Paperwhite and "weeks" for the Libra Colour, per each spec sheet, neither independently verified here.
The closing verdict, segmented: library borrowers in Libby countries get the Kobo; Amazon store loyalists lose little and keep their storefront; sideloaders and EPUB buyers should look at Kobo or PocketBook. What remains unknown is whether Amazon loosens its conversion pipeline — the 2022 EPUB change came suddenly, and the terms can change again.
