The ASUS ROG MAXIMUS Z890 HERO is the objective winner of this comparison, securing more victories across the evaluated specifications. Its most significant advantage is the inclusion of M.2 slots, which offer a 100% improvement over the alternative. This substantial increase in storage connectivity provides a clear lead in hardware capacity, establishing the board as the superior choice for users who prioritize high-density storage configurations and advanced motherboard features.

Users should select the ASUS ROG MAXIMUS Z890 HERO if they require the maximum number of M.2 slots for extensive high-speed storage expansion. Conversely, the ASUS TUF GAMING B860-PLUS WIFI is the preferred option for those who specifically need more PCIe x1 slots, as it holds a 100% advantage in that category. Choosing between these two components depends entirely on whether your build demands superior storage density or increased expansion card connectivity.
