Realistically, there isn't much difference between motherboards. They don't play any part in performance gains or losses, they just provide features in different ways or different quantities. If you need, say, integrated wifi, or 2 m.2's, or 4 m.2's, that is what should narrow down your motherboard choice. Beyond that, there isn't much difference.
Yes, some have more robust VRM's, but realistically any Z390 board from a reputable name (EVGA, Asus, Gigabyte, MSI etc) will be more than capable. I have a . relatively cheap Z390 board from MSI as I got it for free in a package deal with my 8700k, and it runs my 8700k @ 5 ghz no problem, has never blue screened, and I have recommended it to others.
With that, Asus TUF has historically been pretty solid, and their VRM cooling looks more than adequate.
