Bambu is currently the reigning champ.
I have an X1C with AMS at home. We have a P1S with AMS at work.
FYI, you can run them in non-China (LAN-only) mode. The P1S is air-gapped, meaning no network connection. SD card file transfer only.
At home I usually run LAN-only because it's faster to transfer a file (3 seconds vs 10 seconds... noticeable, but not a game-changer. YMMV).
The Bambu are WiFI only, and limited to a 2.4 GHz network as far as I know.
We also have a Mk 4, which runs and runs. It's quiet and reliable with excellent print quality. It sits on a guy's desk and is constantly printing something. He won't give it up.
The QIDI offerings are solid, with some rough edges. We have 3 at work. They run and run, but the quality of the print isn't on par with the Mk 4 and Bambu and I don't have time to calibrate and tune to get them there. They're working dogs.
QIDI has an ethernet port, if that's important to you.
If I were spending my own money again, I'd go Bambu P1S or X1C. The X1C is much nicer, and is already outfitted for glass- and carbon-filled filaments. The P1S needs minor upgrades... which we didn't do on the machine at work. I'll let you know if we ever wear out the extruder or nozzle.
These days I wouldn't buy a printer that didn't have a built-in enclosure. "Engineering" filaments like ABS and Nylon are much easier with an enclosure.
