I assume skinless chicken breasts? I'm getting 367g per 2k calories for that.
Fish is hard to beat without isolated protein sources. It's both lower in fat, and the types of fat are less damaging (and include DHA and EPA).
It's much more difficult to make as strong an argument against fish on macronutrient based health grounds, which is why it's so often recommended.
We can look at the methionine content (too high -- although this is good for starving people who are getting the minimum nutrition), and heavy metals (this is source dependent, clean water and herbivorous fish have much less), as well as neurotoxins and other carcinogens, and it's still not cholesterol free, but in terms of protein per calorie it's hard to compete with.
At that point, you have to compare the other bad things you're getting with the protein (as above), and the lack of good things (antioxidants).
In terms of animal products, fish is probably the least of evils nutritionally.
What I might do is have complete protein count only up to 50 grams, and then any protein including methionine above that amount no longer counts to the total, because it's counterproductive to health beyond the minimum.
It will make grains look a lot worse, but legumes (except perhaps soy) and probably a lot of veggies look better.
And it will pretty much knock all animal products down off the charts.
I'm not sure what to call that measurement though. Maybe "healthy/good protein", and the excess counts as "Bad protein"
And do the same thing for fat, and carbohydrates.
So you might have good/bad for each category, which could put things in perspective. It's also very intuitive for people to understand -- people know there's good and bad fat, so they can probably understand good/bad protein.
And the fact that there would inevitably be bad protein in some plant products too will show that it's unbiased.

It's because it's not a whole food, and much of the fiber, vitamins, and minerals have been removed with the bran and germ which are gone.
