Isn't a 7800X3D a downgrade from your current CPU in terms of productivity? I thought you would go for a 7950X3D to have the best of both worlds.
In any case, I don't think the number of USB ports, of any kind, wiill be a problem, because both have plenty of them. What could be a problem, and you posted it a few months ago, is that both motherboards use Intel's 2.5Gb Ethernet hardware, and those network chips are flawed. Remember?
So, you can pick a third option that uses a netwok chipset from Realtek or other brand, or go with the more expensive ProArt model to use the 10Gb port it comes with.
Please excuse my bad English.
