ReaderPilot compares e-readers and reading tablets side by side: full specifications, weighted VS Scores and live retailer prices, with a published methodology and no pay-to-rank.
This is a category mismatch inside the tablet category, and the table should be read that way. The iPad Air 13-inch carries Apple's M4 chip, a large laminated display, 5G, Wi-Fi 7 and a price to match. The TCL TAB 10 Gen 4 is an inexpensive Android tablet with an entry-level chip, a modest backlit screen, a card slot and a headphone jack. Every diff row points at the iPad. Almost none of them describe what a reader actually does with a tablet.
The row that decides it is not the chip, which is the one Apple would like you to look at. It is peak brightness paired with screen size. The iPad's panel is bright, colour-accurate and fully laminated, and it is a standard-refresh LCD at a price where the omission of a faster panel shows most in exactly the tasks a large screen invites, scrolling long documents and drawing. The TCL's panel is dim by comparison, fine indoors and weak near a window, and refreshes at the ordinary rate. For full-page PDFs and illustration, the iPad's size and brightness are the purchase. For streaming and schoolwork on a sofa, the TCL's screen is adequate and its price is the purchase.
Each makes a different bargain. Apple spends the budget on silicon most iPadOS software will never use and on a long software-support life, and it charges for both. TCL spends almost nothing and buys a metal body, expandable storage, a large battery for its weight, and a chip that is comfortable with reading and video and slower with anything heavier.
Read as reading devices, the two split on weight and glare before anything else. At 616 g the iPad Air 13-inch is a two-hands-or-a-stand tablet; the TCL, at 395 g and a little thicker, is the one you can hold up in bed for a chapter. Neither carries an anti-glare finish in its specification, so both are glossy panels: the iPad's 600-nit peak fights a window better than the TCL's 400 nits, but neither is a porch reader. For PDFs the iPad's 13-inch, 4:3 page shows a full A4 sheet at readable size where the TCL's 10.1-inch, 16:10 screen needs zooming or landscape. Library and store apps are a wash — Libby, the Kindle app and the Kobo app run on both iPadOS and Android — so the choice is not which books you can open but how comfortably you can hold the page that shows them.
Who is wrong for whom: a household wanting one cheap tablet for streaming, video calls, homework and some colour reading should not pay iPad money for headroom it will not reach. Someone who works in full-page documents or illustration and keeps devices for years should not buy the TCL and expect its screen or chip to keep up. And a reader whose main use is books at night should walk past both, because a backlit slab of either size is the wrong tool for that.
Editor’s note
The iPad Air 13-inch is the hardest iPad to place, and size is why. The chip will run anything the platform can install, and almost nothing at this screen size needs it; most owners will read, browse and take notes on a great deal of headroom. Where it quietly compromises is the display. At this money a standard-refresh panel is a real omission, and it shows in the scrolling and drawing a big screen invites. The lighter, cheaper eleven-inch model with the same internals is the more sensible purchase unless you specifically need the page area.
The TCL TAB 10 Gen 4 is sensibly specified for a specific household, one that wants a single cheap tablet and would never spend flagship money on any of it. The large battery for its weight, the generous storage with a card slot and the headphone jack are real conveniences. The caveats are the screen, adequate indoors and weak near a window, the ordinary refresh rate, an entry-level chip that stumbles on heavy multitasking, and a charger in the box slower than the charging the spec sheet advertises.
Walk past the iPad if you are buying to read; walk past the TCL if you read outdoors or work in demanding apps. TCL's own matte-screen model is the better reading tablet in its range.

Buy the Apple iPad Air 13-inch if you want a large, bright page for full-size PDFs, illustration or light desk work, and you value years of software updates over the last word in display technology. Buy the TCL TAB 10 Gen 4 if the brief is a single inexpensive tablet for streaming, schoolwork and colour reading, where a metal body, a card slot and a big battery matter more than speed.
The trade-off that decides it is what the money buys: Apple's silicon and support life against TCL's price and expandability. For long reading sessions neither is the answer, and an E Ink reader will treat your eyes and your wallet better.
