Dyad is an excellent rim, not too wide, not too narrow, not too heavy, but solid.
I don't know what you were doing to the A23 but I've built with both and never found any difference between them in terms of build. Specification-wise, there is very little difference between the Dyad and the A23. The A23 is 75g lighter (not a huge difference when it comes to aluminum), 1mm narrower (again not much difference), and 2.5mm shorter in depth of rim.
Personally, I'd opt for the A23 over the Dyad to take advantage of the off-center drilling of the A23 and the advantages that it offers for wheel strength over the Dyad. That would increase wheel strength over any slight differences in the rim dimensions.
