Although I'd probably just throw my UPS away and put in a power station these days.

I have a very popular CyberPower CP1500PFCLCD I bought back in 2019, that is now approaching 7 years on its original SLA batteries (still working though). I was debating upgrading the SLA's to LFP or just stick with a UPS capable power station. One nice about a True UPS like the the cyberpower is that its switchover time is ~4 ms, compared to my current EcoFlow Delta 2 at 30ms, and the Delta 3 at 10 - 15 ms. Both which are far faster than my Tesla Powerwall 2's at ~400 ms.
I had encountered a UPS issue when I upgraded my PC to a RTX 5090 where UPS would start tripping over 1000W, but I solved that by downgrading my 5090 back to a 5080, so my power draw now is back to 700-800W.

Dedicated UPS are nice if you need that ultra-fast response time for extremely sensitive gear but for a computer with a good quality PSU, anything under 20ms is fast enough, and any good power station should be able to hit 15 ms or faster for their UPS mode.
I know I got a River 3 Plus that has <10ms switchover, but the voltage regulation is horrible, it can be as low as 70v and as high as 140v before it switches over to battery. I was using it on a home theater setup (TV, speakers, desktop computer, Roku and network switch, like 180w when everything was on) and in brown outs, the PC would reboot.
I ended up keeping my old APC with a bad battery and plugged that into the wall, then the River 3 Plus is plugged into that, so the APC will try to switch to battery when voltage gets below 109v or above 130v (what I set it to), and since the battery is dead, it cuts power, and the River 3 switches over to battery. This has fixed the issue for me, but is not ideal. I also have a River 3 Plus on my network gear, but since all that does 120v to 12v, it does not seem to care.
Not sure if the Anker/Bluetti/Oupes models have the same issue.
