Gigabyte Z690 AORUS PRO DDR4. I'm very happy with it. Stable and does the job. BIOS seems good to me, no complaints. Can't comment on RGB stuff because mine's in a closed black box. Not sure what NIC it has... specs online say "Intel 2.5GbE LAN chip", my router is only 1Gb but it works fine, no disconnects. PC is Windows only though. I've mostly had Gigabytes over the years (some Asus as well), and haven't had a lemon motherboard yet, maybe I've been lucky. But I am pretty demanding and don't tolerate faulty stuff well. I'm also quite annoyed by noise, system is set up to be as quiet as possible with passive PSU/140mm fans/etc. Haven't noticed any coil whine.
