When I bought my power supply several years ago, I went with the highest rated one from johnnyguru at the time which was an EVGA one. It is only one anecdote but at the time at least, the G3 EVGA power supply came highly recommended from johnnyguru with comprehensive tests completed.

IIRC the EVGA G3 failed the ATX requirement of holding voltage after mains goes down, dropping way too quickly. It was the only one of several that they tested in a group review. Not sure how much storage vendors relies on those milliseconds, but I decided to get something else.

I wish the site was still up because I swear the EVGA SuperNova G3 was the highest rated power supply johnnyguru ever reviewed. Their review from my memory never covered that. I may have that all wrong seems multiple people remember the issue.

To be fair, it rated well on most other aspects as I recall.

I found a review by Tom's Hardware where it barely passed the minimum[1]. It's not unreasonable small differences between PSU units and measurement equipment leading to it just failing for some other reviewer.

To be fair, I recall it was rated well in other categories, and the Tom's Hardware review does as well.

G2 was the only ever recommended, G3 had issues with some protection circuits.

I do not remember that and this is the first I have heard of that issue. My G3 has had zero issues in 5 years of operation. Do you happen to have a link to that?

Seeing as johnnyguru is not available as far as I can tell this is the only proof I have: https://www.reddit.com/r/buildapc/comments/5kl4v0/jonny_guru...
