Business class international on Delta is far more than that. I know, I fly Delta first-class often enough and that's ~100k/roundtrip domestic. So that would be five first-class domestic flights for me and a partner at 1MM miles. Business class international? Might get one roundtrip flight between the two of us with some leftover miles for domestics.
They all suck. It's a race to the bottom. Delta is at least upfront about it and their FF program IMO is overall the best (behind American) depending on your geographic location and actual desire to fly (and not run miles like your life depended on it).
A UA saver award on business is 115k miles roundtrip international. You could fly from San Francisco to anywhere in Europe in business class and back for 115k miles + ~$10.
