I would go DT Swiss even though I don’t have any experience with either. I have friends who run the GR1600 and GR1800 and love them. I’ve held both in hand, and can attest to how nice they “feel”.
FWIW, I just picked up an Easton EA70AX wheelset and its fantastic. 35mm Gravel Kings are measuring at 38mm on the 24mm internal diameter rim.
