I've tested a ton of readers and formats. The Kindle used to be the go-to for mobi, but since Amazon phased it out, most devices now focus on epub. My absolute favorite is the Kobo Libra 2—it handles both formats like a champ, plus it has a gorgeous screen and supports OverDrive for library books. PocketBook is another solid choice, especially if you need advanced formatting options.
For a more budget-friendly option, the Onyx Boox series is fantastic since it runs Android, letting you install any reading app you want. I sideload epubs all the time using Moon+ Reader, and it works flawlessly. If you're into open-source solutions, Calibre isn't a device, but it's a must-have tool for converting between formats and managing your library before transferring to any reader.

My journey with e-readers has been a bit of a rollercoaster, especially when it comes to finding the perfect one for EPUB files. After testing a bunch, I keep coming back to Kobo devices. The Libra 2, for instance, handles EPUB like a dream—no weird formatting issues, and the screen is easy on the eyes for long reading sessions. Plus, their built-in OverDrive integration is a lifesaver for library books.
What really sold me, though, was the customization. You can tweak fonts, margins, and even add your own EPUBs without jumping through hoops. Some folks swear by Kindle, but unless you’re okay with converting files or sideloading, EPUB support is clunky. Kobo just feels like it was made for readers who want simplicity and flexibility.

Don't sleep on the fact that many browsers can be makeshift ebook readers. Microsoft Edge has a pretty decent built-in EPUB reader. You just drag and drop the file into the browser. It's not a library manager, but for quickly opening an EPUB you just downloaded, it's shockingly competent. No MOBI or AZW3 support, though, so it's a partial solution.

I bounce between a handful of stores depending on what format I need, and for epub + mobi support the usual suspects are pretty reliable. Kobo and Google Play Books are my go-to for epub — they sell DRM-protected and DRM-free epubs depending on the publisher, and their files are clean and work well on most apps. Smashwords is a treasure trove for indie writers: they often provide both epub and mobi downloads, and many self-pub authors upload both so you can grab whichever your device prefers.
Project Gutenberg and the Internet Archive are perfect when I'm hunting classics or public-domain texts; they routinely offer epub and Kindle-format (mobi) files. Feedbooks and ManyBooks are also great if you want a mix of classics and contemporary indie works — both usually provide multiple formats. For libraries, OverDrive/Libby typically lends epub files (with Adobe DRM), and historically they also interfaced with Kindle for borrowing, though the exact workflow has shifted in recent years.
A heads-up: Amazon's Kindle Store uses its own proprietary formats like AZW/KFX now, but you can sideload mobi or use 'Send to Kindle' which converts epub into a Kindle-friendly file. If you ever need conversions or tidy metadata, Calibre is indispensable. Just watch out for DRM — removing DRM can be legally murky, so check the store's terms before you tinker.

I've tested several devices and can confidently say the Kindle Paperwhite (2024) is a top contender for EPUB and PDF support. Its 6.8-inch glare-free display makes reading comfortable, and the adjustable warm light is perfect for late-night sessions. The Kindle ecosystem now fully supports EPUB via Send-to-Kindle, and PDFs render clearly with zoom options. Battery life lasts weeks, and it's waterproof—ideal for poolside reading.
Another stellar option is the Kobo Libra 2, which handles EPUB natively without conversion. The 7-inch screen and physical page-turn buttons are a joy to use, and its PDF reflow feature fixes formatting issues. For Android lovers, the Onyx Boox Note Air3 offers a 10.3-inch E Ink tablet experience with built-in annotation tools for PDFs. These devices balance format compatibility with reader-first designs.

let me tell you, the Kobo Libra 2 is my absolute go-to for format versatility. This thing eats EPUBs, PDFs, MOBI, and even obscure formats like CBZ for breakfast. What really sets it apart is the native support for Adobe DRM without jailbreaking – something Kindle users can only dream of. The built-in OverDrive integration means I can borrow library books directly without format conversion headaches.
The screen's crisp 300ppi display handles manga and PDFs beautifully, unlike some readers that choke on complex layouts. Pocket support lets me save articles from the web to read later, which is a game-changer for research. The only format it struggles with is Amazon's AZW, but that's what Calibre is for. After bricking two Kindles trying to sideload EPUBs, I'll never go back to locked ecosystems.

I always look for apps that handle both EPUB and PDF seamlessly. My go-to is 'Calibre' because it's not just a reader but a full library management tool. It supports almost every format imaginable, including EPUB and PDF, and lets you convert between them if needed. I love how customizable it is—you can tweak fonts, margins, and even the lighting to match your reading preferences. Another solid choice is 'FBReader,' which has a clean interface and syncs across devices. For PDFs, it’s a bit basic, but it gets the job done. If you want something more polished, 'Lithium' is a sleek option for EPUB, though PDF support is limited. Honestly, the best combo I’ve found is using 'Calibre' for organization and 'Moon+ Reader' for actual reading—it handles both formats beautifully and has night mode, which is a lifesaver for late-night binge-reading sessions.
