The MSI MAG X870 TOMAHAWK WIFI is the objective winner of this comparison, securing a lead in seven out of thirteen evaluated specifications. Its most impactful advantage over the ASRock B760M PG Lightning is the inclusion of double the number of M.2 slots, representing a 100% improvement in storage expansion capability. While the ASRock B760M PG Lightning holds its own in specific connectivity areas, the MSI MAG X870 TOMAHAWK WIFI provides a more robust foundation for modern system builds.

Users who prioritize high-capacity storage configurations should choose the MSI MAG X870 TOMAHAWK WIFI for its superior M.2 slot count. Conversely, the ASRock B760M PG Lightning is the better selection for those who specifically require more PCIe x1 slots for peripheral expansion, as it offers a 100% advantage in that category. Selecting between these two motherboards depends entirely on whether your build requires extensive high-speed storage or additional legacy-style expansion card support.
