Just in case, I have the Gigabyte Z490 Aorus Ultra running my 10700K. It is rock solid, great at overclocking. The VRM in a true 12 phase works great and never gets hot as it has a proper fin stack to cool. There is a driver issue with the 2.5GHz nick which sometimes resets, but as the board also has Wifi 6 it is not too much of a pain but hopefully a driver update will resolve this. Apparently this is an Intel issue.
The one downside is the BIOS which is still behind Asus and MSI and could be improved, though they never seem to get on top of this. Still the Bios works fine, has pretty much everything and is straightforward for overclocking. I would go as far as saying the overclocking on the Z490 is even easier than before.
