To me, it feels in between. The pattern regular definitely feels a little smaller than the wide-fat, but it feels wider than the DGT. I occasionally find myself bending strings off the neck of the DGT...that doesn't happen with the WF, Pattern, or Pattern Regular. The DGT neck feels deeper (front-to-back, not side-to-side) and also has a very subtle V-shape...well, at least my 2009 DGT does.
My preference of all PRS necks is the Pattern carve that was used on the Signature Limited...that feels like a WF with slightly rounded shoulders. The pattern regular is similar, but just a little shallower (front-to-back).
I suppose there is some individual variation due to hand sanding, but the 2 guitars I have with pattern regular (XPRS Artist Package P22 and a 513) feel very similar in shape, even though they are different woods and finishes.
