The MSI MEG Z890 ACE is the objective winner of this comparison, securing more individual specification victories than its counterpart. While both motherboards share several identical features, the MSI MEG Z890 ACE provides the most significant technical advantage in its networking capabilities, offering a LAN performance that is 100% better than the alternative. This superior connectivity serves as the primary differentiator between the two boards when evaluating their overall hardware configurations.

Users who prioritize high-speed network throughput should choose the MSI MEG Z890 ACE to take advantage of its superior LAN specifications. Conversely, the MSI MAG B860 TOMAHAWK WIFI is the better selection for builders who require additional expansion options, as it offers a 100% advantage in available PCIe x1 slots. Selecting between these two components depends entirely on whether your specific build requirements favor enhanced networking infrastructure or increased physical expansion capacity.
