The ASRock X870 Steel Legend WiFi is the objective winner of this comparison, securing a lead across six of the fourteen evaluated specifications. Its most significant advantage over the competition is the inclusion of USB Type-C connectivity, which offers a 100% improvement in that specific category. While both motherboards share several identical features, the ASRock X870 Steel Legend WiFi provides a more robust overall configuration based on the total count of superior technical specifications.

Users who prioritize modern peripheral connectivity should choose the ASRock X870 Steel Legend WiFi to take advantage of its superior USB Type-C implementation. Conversely, the MSI MAG X670E TOMAHAWK WIFI remains the better option for builders who require additional expansion capabilities, as it holds a 100% advantage in available PCIe x1 slots. Selecting between these two components depends entirely on whether your specific build requires more versatile external port options or increased internal slot density.
