People put way too much stock in the whole "made in Japan" thing. Not all batteries made in Japan are good, nor are all batteries made in China bad.
You are correct that the Energizer NiMH are usually made in Japan, however they are definitely not rebranded Eneloops. They have different physical and electrical characteristics. Strangely, there's a huge difference between the 2000mAh and 2300mAh version. The 2300mAh version are garbage, while the 2000mAh seem fairly decent.
I know people often bring up the supposedly rebranded Eneloops, such as the IKEA Ladda or Watson MX/CX but I'm not convinced they're as good as genuine Eneloops. The ones I've tested have been quite inconsistent, unlike real Eneloops, which have all performed virtually identically. Also, a site that did long term testing had rebranded Eneloops at the bottom of the chart, while the genuine ones did quite well.
As an alternative, the Ikea Laddas are supposedly rebadged Eneloop Pros at well under $2/battery. Ive been running those and have been happy with the results.

I have the energizer charger from Costco, assuming that would be ok to use here.
Ikea ones are bigger bodies on some places where eneloop or energizer just fits just fine. And some say specifically not to use rechargeable (reason for buying disposable).
I bought ikea every year during birthday a year when ikea used to send $10 coupons. Otherwise buying energizer from costco when it is on sale.
All kids toys, mouse, even clock uses rechargeable. I keep the disposable comes with toys for occasional use or gifts (toys for other kids when it didn't come).
I think I only once bought disposable AA last year (still 60% in it, only using for the smoke detectors).
As far as price, if you like eneloop then this is good price. Not everyone got ikea or costco near by. Otherwise, the quality on them is fine.
Anyway all companies get sold to x and y, changes quality. Few still stand after being sold, like eneloops, Metabo hpt, etc. Few struggling and standing like Yamaha, sony, etc.
What PF does may make sense for the batch he did. I only stick with branded rechargeable opposed to cheap brands, only because the possibility of damage can be done to modern electronics by cheap ones.
LSD is the way.
If you need battery, this is an ok deal. The 8 pack is bit cheaper than this.

If I were buying a charger now, I'd probably get this, though I have no experience with it

Any device that allows batteries to run down very low before quitting will damage rechargeable batteries, which unfortunately is nearly everything. The problem is made worse when you've got unbalanced batteries, so that one will run flat while others still have good voltage.
Batteries can usually be recovered by forcing them to recharge, then running the refresh mode which will charge and discharge them until capacity stops improving between cycles.

While there are circumstances where people may get close to these numbers, the average person (even with the best charger) isn't going to come remotely close.
The Project Farm videos are interesting and informative but I do have some issues with his methodology.
Here [aacycler.com] is a site that has done some long term testing. I find the high capacity AA results interesting. The Panasonic Eneloop Pros rank 7 out of 39. The Japanese IKEA Ladda, Duracell Ultra, and Fujitsu Black are in 35th, 36th, and 37th place. They only beat the Panasonic 2700mAh (which I don't know the origin of) and Energizer 2300mAh (which I too have found to be awful).
I have some Rayovac Hybrid 2100mAh from 2007 that are still going. They Rayovac Hybrid/Platinum are the best NiMH I've used. It's a shame they don't make them anymore.
Don't quote me on this but I vaguely recall seeing evidence of a few people getting them.
They may be cheaper but both Powerowl and EBL massively overinflate the ratings of their NiMH batteries. Just look at the user reviews of those who actually tested them. I haven't personally tested any Powerowls but I did test the 2500mAh EBLs and they're closer to 1850mAh.
I suspect this is the case. However, evidence and my own experience suggests some of them are really low quality. Out of the dozens of batteries I've tested, one Watson CX (rebranded regular Eneloop) was the only cell that arrived totally discharged (0.9V).

Look up the paper clip trick.
​
I use the scissors method.
The Powerowl have 200 mA more capacity, meaning if you were to mix the Eneloops with Powerowl, the Eneloops would have a lower depth of discharge, accumulate wear faster, and fail sooner.
All of this is moot, because devices kill batteries because they discharge them too deeply, so what you want is a lower cost cell that can be replaced at a lower cost once you've ruined them.​
