Clean Wing: they seem to have put quite the effort into that. no thrust gates ..
Airbus seems to ( OK, I am certain use thicker profiles that are stil perfectly supercritical.
Static height brings stiffness with the 4th exponent?
MY tentative guess is that the Airbus wing is lighter _and_ stiffer for comparable lift.
Especially the bendy 787 wings need thicker skins to carry moment forces along the wing.
