Where did get the wind readings for both pickups. I'd like to get that too, just for fun.
The ohm reading doesn't give you anything on output except that if it's on the hotter or lower side of output (roughly over or under 10kohms) The EQ reading SD and DM give to their pickups don't tell what they are compared to each other. All SD pickups seem to be scooped mids and DM has only one or two that come even close to that EQ-curve. They most likely use different scales.
IMO, the only way to determine which pup has more output is to play them both.
Btw, the X2N is pretty sick pup. It's not warm or bright but very even. It's the hottest pickup DM makes so I see no reason why DD should even have to be hotter. Both are fine pickups.
I have the X2N-7 on a doubleneck on a 7-string baritone neck.
