I use the X-pattern for one reason. I don't really believe all the other arguments (not much of a believer here:shrug:), but I know this one to be true:
Many razors don't make perfect contact with the hone's surface. The slightest warp or twist in a blade, or curve in the edge results in some parts of the edge touching the hone while other parts remain underhoned. Performing the X-stroke shifts the points of contact and in most cases deals with any contact issues. If not, the next thing to do is "the rolling X-pattern.
All the reason I need to prefer the narrower hones and the X-pattern. The issue of the heel receiving too little attention is easily solved by "curving" the X's a bit, so that the heel stays a bit longer on the hone.
