I've used the EB contour on my go-to guitar for the last five years. I find it particularly comfortable for 1st-position playing despite the fact that it does put more meat under the thumb for a given thickness. However, I recently replaced the neck (for several reasons), and I chose a standard C profile of the same thickness (0.85", slow taper). For me, the C is a better overall compromise, but I still have another guitar with the EB... and it's going to stay that way.
