Roll left or right in flipturn????

I would do a poll but don't know how. My pool does not circle swim. I have my own lane. When I learned to flip turn I roll to the right i.e. when I roll I will be looking left when I break out. When I occasionally circle swim, I find this to be aqward and have difficulty heading to the right side of the lane on pushoff. My question is, do coaches prefer teaching one over the other?
