The ASUS ROG STRIX Z590-E GAMING WIFI is the objective winner of this comparison, securing more total spec victories than its competitor. Its most significant advantage is the inclusion of M.2 slots, which offer a 100% improvement over the Gigabyte B550 AORUS PRO AC. This hardware configuration provides a clear lead in storage expansion capabilities, making it the superior choice for users prioritizing high-density drive support within their system build.

Users who require extensive high-speed storage should select the ASUS ROG STRIX Z590-E GAMING WIFI to utilize its superior M.2 slot capacity. Conversely, the Gigabyte B550 AORUS PRO AC is the better option for those who specifically need additional PCIe x1 slots, as it provides a 100% advantage in that category. Choosing between these two motherboards depends entirely on whether your specific build configuration demands more internal storage drives or additional peripheral expansion cards.
