Yes, people ignore the value of these batteries. Pretty much nothing else comes close in terms of price per battery or price per Ah. While EBL and a bunch of others are also cheap, nearly all of them seem to have massively overstated capacities. The 2500mAh EBLs I tested were actually roughly 1850mAh. The Amazon Basics batteries I've tested average at least roughly their rated capacity, in some cases greatly exceeding it. The made in China 2400mAh ones I tested mostly exceeded their rating.
While costly, actual Eneloops do seem to be the best quality. They are extremely consistent and come the closest to precisely hitting their rated capacity (no more, no less). I can't say for certain but I suspect at least some of the rebranded Eneloops are either rejects or ones that didn't meet the quality standards to be actual Eneloops. Some of the ones I tested (especially the Watson MX/CX) were much less consistent and showed evidence of high self-discharge. Interestingly, the 2550mAh Watson MX averaged slightly higher capacity than the 2600mAh Eneloop Pros.
For starters, those are AAAs, not AAs. Secondly, they're ten times the price ($7.50 vs $0.75 each). I don't know where you got 2250mWh from but that's just plain wrong. Lithium-ion AA/AAA are a whole different beast, and not always for the better. Nearly all of them are from no-name companies, of questionable quality, and use proprietary chargers. They almost always have higher self-discharge than a decent NiMH because they have to continuously power the regulation circuitry. That circuitry can also cause interference or other issues with some devices. The ones with built-in USB charging sacrifice considerable capacity to accommodate that feature. The ones you linked are 750mAh. A standard capacity NiMH is usually at least 800mAh. Some can reach almost 1100mAh. Also, the reviews for those batteries are almost entirely from people who got them free. Not that I put too much faith in Amazon reviews anyway, since I've seen plenty of garbage products with seemingly great reviews. In my opinion, lithium-ion AA/AAAs are more for niche purposes, powering devices that won't tolerate NiMH.
EBL is not a good brand. Most of their batteries have outright fraudulent ratings.
Manufacturing location is not a reliable indicator of quality. There are garbage batteries made in Japan and quality ones made elsewhere, including China. In recent years, Amazon sells ones made in either Malaysia or China. Sometimes it even varies depending on the quantity you buy.
They definitely do. Cycle through the various listings/quantities and you'll see it vary between made in China and made in Malaysia.

Amazon Basics Regular Rechargeables (2000mah) = BAD [Many previous deals]
I've found these HC 2400mah ones to be on par with other brand 2000mah batteries. For less than $1/battery, these are well worth it. Conversely, I wouldn't buy the non-HC ones again.

It turns out they are *slightly thicker* than most AA batteries and can get stuck in some electric kids toys.
Since stupid kids toys are the main reason I blow through batteries, I don't recommend these.
I had these for over a year, no issues. Just bought more. Use these in xbox controllers, last around 2 weeks of gaming for 1-2 hours a day.

I have both these and the "regular" 2000mah ones, and these are noticeably better. I suspect many of the bad reviews are for the standard capacity ones.
The next cheapest NiMH battery right now is EBL at $1.47 - $1.62 at Amazon right now. And the reviews for those are, likewise, mixed, but generally favorable.
If you want NiMH perfection you are looking at Ladda at $2 a battery if you have an IKEA nearby, or Eneloops at $3-4 a battery.
