New-Glenn has a low thrust to weight ratio vs other rockets and lower engine chamber pressure than some other engines to put less stress on the rocket and engines for greater reusability.
But the obvious cost here is less mass to orbit. But I suspect it's a given that they'll tweak up the margins once they have more flights under their belt.
