Green/Cement Board Overlapping Tub Flange vs Leaving Gap Between Board and Flange
It looks like this subject has been beaten to death on the internet but there doesn't seem to be a consensus, so I thought I'd ask you guys which is better. I'm looking at using Swanstone tub walls with a Kohler tub.

The second method, leaving a gap, seems the simplest since you wouldn't need a 1/4" thickness transition with the rest of the bathroom walls. Is there any reason to choose one method over the other, or does it not really matter?
