optics: ASRock Fatal1ty Z270 Gaming K4 / ASRock Fatal1ty Z270 Gaming K6
performance & utility: Gigabyte Aorus GA-Z270X-Gaming 7 if the white heatspreaders don't bother you, otherwise the Gaming 8, but it's priced significantly higher atm.
the Gigabyte Aorus GA-Z270X-Gaming K5 is a bit cheaper but might just be what you need. the Killer Ethernet chip surely is a plus.
ASUS would be the go-to but their lineup is all grey and with little RGB so far.
MSI has some boards in their lineup, if you dare to touch them.
don't know about MSIs software though.
