Our verdict
For remotes, clocks and toys, either will do the job. Energizer makes the stronger performance claim, up to 50% longer lasting, with a leak-resistance promise and a 7-year shelf life, so pick it for devices that draw more power, such as controllers or torches. Amazon Basics claims a 10-year shelf life and suits stockpiling for low-drain gadgets. The packs differ in size, so count cells, not packs.

Claims on each pack
The Amazon Basics pack lists 20 1.5V AA alkaline cells with a 10-year shelf life, a double-crimp design and a leak-free claim. The Energizer pack lists 24 cells with up to 50% longer lasting power, a 7-year shelf life, a leak-resistance promise and recyclable packaging. The 50% figure is Energizer's own comparison and the listing does not show its basis in the text we read.
What alkaline AA means in practice
Wikipedia lists alkaline AA capacity at roughly 1,800 to 2,850 mAh and 1.5V, and notes that capacity drops as the drain rises and that alkaline cells are more prone to leaking than lithium. That is why high-drain devices burn through alkalines quickly, and why leak claims matter for devices that sit unused.
Rechargeable or lithium instead
The Amazon Basics listing says these are not rechargeable. For high-drain gear, Wikipedia says lithium or NiMH hold up better under heavy current. Rechargeables suit controllers and cameras used often.
Pack size and who should skip both
Check cell count per pack: 20 against 24. For button cells instead, see Duracell vs GP CR2032 or the batteries category.
