I've been running a HX750i for 4 years now, and it's done well overall. Just ordered a HX850i from OCUK (part of that 26/02 delivery, hopefully) to help accommodate my 3090 and give a hand-me-down for a frankenstein PC for my GF. I just couldn't find a "definitely better" option around, that was both available and priced ok. I like the USB connection for monitoring power, which surprisingly isn't available on more devices out there?
