The MSI MEG Z890 ACE is the objective winner of this comparison, securing more victories across the evaluated specifications. Its most impactful advantage is the inclusion of USB Type-C ports, which offer a 200% improvement over the alternative. While the ASUS TUF GAMING B860-PLUS WIFI holds its own in several categories, it falls behind the MSI MEG Z890 ACE in total spec-win count, despite providing a 100% advantage in the number of available PCIe x1 slots.

Users who prioritize extensive peripheral connectivity and high-speed data transfer should choose the MSI MEG Z890 ACE for its superior USB Type-C capacity. Conversely, the ASUS TUF GAMING B860-PLUS WIFI is the better selection for builders who specifically require a higher density of PCIe x1 slots for expansion cards. Your final decision should depend on whether your system configuration relies more heavily on modern external connectivity or internal slot-based hardware expansion.
