The Cyberpower series sold at Costco is unironically good. No frills or cool stuff, UI from 1995 but supports USB monitoring out of the box and just… works. I was about to make the brother comparison but after reading your entire comment realize you already did it.

Just FYI, Cyberpower, at least for their consumer line, use problematic yellow glue[1] which becomes brittle over time and can become conductive, causing arcing/fire hazards[2][3]. There was also a prior HN discussion about it[4], with some similar experiences.

It can be removed[5], with some effort, though. Given its use in various electronics it wouldn't surprise me if some other UPSes use it, though have only seen discussions about Cyberpower.
