The MSI MEG X870E ACE MAX is the objective winner of this comparison, securing victory in eight out of thirteen evaluated specifications. Its most significant advantage is its LAN capability, which outperforms the ASRock B760M PG Lightning by 300 percent. While the ASRock B760M PG Lightning holds a 100 percent advantage in the number of PCIe x1 slots, the MSI MEG X870E ACE MAX dominates the overall feature set across the majority of the measured technical categories.

Users who prioritize high-speed networking and advanced connectivity should choose the MSI MEG X870E ACE MAX for its superior LAN performance. Conversely, the ASRock B760M PG Lightning is the better option for builders who specifically require a higher quantity of PCIe x1 slots for their expansion needs. Selecting between these two motherboards depends entirely on whether your build demands the networking throughput of the MSI board or the specific slot configuration offered by the ASRock model.
