Starting with the ASUS.

Pros:
- Cheapest board of the three ATM ($370 CAD)
- Has the most USB-A ports, and most are 10 Gbps
- No lane sharing between M.2 and PCIe slots, GPU will have 16 lanes no matter what

Cons:
- No USB4
- Uses debug LEDs instead of a post code display
- Wifi 6E only (but to be fair I don't have a WiFi 7 network, plus I use Ethernet, speaking of which...)
- Uses the Intel i225 ethernet chipset, which has a history of stability issues. Not really clear if those have been fixed or not.
- ASUS warranty is also not the best from what I've heard so I'm probably on my own if this breaks it seems.
