I use “PDF Studio” (https://www.qoppa.com/pdfstudio/) and it’s great, no problems at all.
Sadly I have to keep one Windows machine with Acrobat installed because the tax authorities here use hideous Cthulhu-like many-tentacled “Dynamic Forms” documents that automatically transform into XML (ugh) and only work in Adobe/Windows. But other than tax returns, I only use PDF Studio.

I just read the manual for the Euro version; basically, they assume you take the power strip/PDU with the computer.
So, you plug the special UPS into a spare outlet on the PDU; it monitors the power supply, and as soon as power from the PDU drops it jumps in and starts supplying. So plug into an outlet, then unplug the PDU from power, and the UPS takes over. Since at this point the pins on the PDU plug are live, they provide a safety cap to put over the end of the cable. The computer itself is never unplugged.
