It wasn't my assumptions that was wrong, my research (early days of the Pi5) suggested it. Which matches the github issue where the belief was that PPS was supported.

But even if that was the case you shouldn't blindly buy one where the specs match.

Is it good quality, is it made for 24/7 operation, does it get hot etc.

In the Pi case it is quite simple. The official one isn't expensive and it is ubiquitous. It runs fine on most supplies though if you need one in a pinch. But I do recommend going for the official one for long term use.
