I have dealt with a lot of units over the years, both consumer and professional. I have had more non-battery issues with APC ones than the Cyberpower ones, especially with the rack mount units.

For batteries they all have a lifetime, so I don’t trash a brand simply because the battery dies. That will happen to any UPS battery. However it is well known that APC floats the batteries too high resulting in slightly more runtime at the expense of battery longevity. I have replaced more APC batteries as a result.

All of that said, at the consumer level I just tell people to go buy whichever one is on sale at that moment since at least one of them usually is.
