Here's a quick rundown of the differences between both boards:
Starting with the bundle, the MEG Z390 ACE lacks M.2 expansion card and ‘Streaming’ card (likely a capture card). The ACE also lacks onboard OLED screen, which can be seen on GODLIKE right next to 24-pin power connector. The cheaper MEG motherboard will only have one M.2 shield, as opposed to GODLIKE, which has three.
The power section has also been downgraded. Although the board still features two 8-pin power connectors (GODLIKE is 8+8+6), the VRM is 13 phase, while GODLIKE features 18-phase power delivery.
The ACE is equipped with onboard WiFI, but it does not have two Ethernet connectors like GODLIKE.
