Yes if you want to get into detail, one should compare environmental cost per calorie. Even then, beef still is worse than chicken and most vegetables.
I recognize that some vegetables are far more resource intensive than others, which is why I stated 'the average' vegetable. If we wanted to shift diets towards being more environmentally friendly, we'd have to be selective and deliberate about how we do it.
I would argue that shifting diets rather than trying to get everyone to become vegetarians (that don't eat lettuce) is the most sensible path. It would be hard to convince everyone never to eat a steak again, but if you can get people to go from eating 50 lbs of beef a year to 30 or 40 lbs and shifting to chicken and legumes it could make a sizable difference. Would be even better if the developing world went straight to sustainable diets rather than roaring towards beef-heavy diets.
