Which one for your work

Each card is decided by one number both models carry. Where only one has it, the card says so and makes no call.

Benchmark by benchmark

First the score: boards each model leads, per category, where both have a result. Then every board, a category to a fold; bars are each result on a 0 to 100 scale, so compare the two in a row, not one row with another.
