I have a lot of different ones.
Cyberpowers seem to burn out. Perhaps they take the hit and don't recover, I have had several fail to work after a year or so. Not easily replaceable batteries and didn't keep up with the receipt to take back. I can still use the non battery sections so I move them to less important equipment for surge protection. I like the software with the cyberpowers better than any of the others.
APCs seem to last forever and have replaceable batteries for the most part. No real software, works with windows. Costs more but the replaceability makes up for that.
Couple of off brands that seemed to have died. I will stick with those two.
Figure out how much energy you need to protect. Routers and such take tiny amounts and can usually be put on the same line as a server or another computer. Exclude printers, especially laser printers, they are energy hogs. I do not have my screens on backup. This is more from the days of CRTs, the newer LCD and LEDs do not take that much energy. They seem to be fairly fault tolerant though. 500 should handle a modest server. 350 for a basic computer. 1000 will handle most, maybe even 2. Cost is roughly divided by 8 to 10.
