There is no useful difference between the two.
B360 has raid capability which should be useless to most as well as potentially more usb 2.0 ports.

If I was looking for a 300 series lga1151 motherboard, I would consider one with a Z370 chipset.
That will allow you to overclock a future "K" suffix 8xxx processor.
