Well, it's a Z270 board, and, for the most part, they're all going to be the same, electrically, because they have to follow Intel's spec. If you look at the boards individually and compare them to each other then you're going to find small differences, like Bluetooth, WiFi, and stuff like that, but otherwise, a Z270 board is a Z270 board—pick the one with the prettiest colors and/or best warranty and run with it.

Other than that, outside of CPU, GPU, and RAM, which are good, the rest is pretty much just personal preference.
