The expression "birds are maniraptoran theropods" is more informative 
than either one (and more easily subject to falsification, however that 
might work in systematics).

And no one (that I know of) says "birds are descended from amniotes" or 
"birds are descended from vertebrates", or even "humans are descended 
from mammals".
