✅ 1 additional PCI-Ex 1 slot can be used for various expansion cards

✅ It has a onboard USB 3.1 Type C header which is very beneficial in many cases

✅ Both of it's M.2 sockets support SATA as well as PCI-E modes which means better compatibility

✅ It supports Quad SLI and Quad CrossfireX. Although, it's not a big advantage in general

✅ It has 1x DVI port which can be used to connect to a monitor not having having DP or HDMI ports

✅ It has 2 more USB 3.1 ports over Asus Prime Z370-A at its I/O

Both the motherboards are close in price and in most of the features but the most important feature that ASRock Z370 Extreme4 leaves behind the Asus Prime Z370-A is overclocking for both the CPU and Memory. Although, there are some features that are better in Asus Prime motherboard but if you are looking for a motherboard particularly for overclocking, then ASRock Z370 Extreme4 is the way to go.
