The Costco batteries are lithium ions marketed by Coast. They are very similar with usb-C charging cables. Please try to not be so condescending.

One thing worth noting is that the Costco AA batteries were 2,400 mAh while these are reportedly 3,600 mAh (edit: the Amazon page says both 2,400 and 3,600 — I don't know which is correct), so you're getting more capacity here. I can't really say whether the Costco ones were higher quality since I've never heard of any of these brands, but if you're after long-lasting 1.5V AAs, this looks like your best bet right now. Just because one store had a stock clear out price that was cheaper at one point doesn't mean this can't be a good deal as well.
Of course you could always wait and see if Costco ever brings back that set the OP mentioned. Here's the SD listing:

Re: Costco deal - the AAs are fine but lithium AAAs usually have less capacity than NiMH, the circuitry to get them to work at 1.5V takes up too much room in the AAA form factor.
Edit: 2400mAh x 1.5V = 3600mWh.

2,400mAh means if you discharge it at 2,400 mA it will last 1 hour. In reality it's less, because the rating is provided under much smaller discharge current, but that's the gist of it. 1.5V is the voltage it produces. Note that for many of these batteries it will not be 1.5V for the whole discharge cycle. Rather, it will drop abruptly to a significantly lower voltage (1V or so) well before the 2,400 mAh are used.

Can you explain a bit more about "green choice"?
Li-ion cells are naturally 3.6V+ and this product seems to have a built-in charger, BMS and DC-DC converter to provide 1.5V. I wonder if this is using more resources to achieve AA/1.5V spec.
