However I measured with U2 seat pocket empty.

I do agree this is a personal interpretation in one sense - some seats work better for different people. But the knee room at every point on BA is greater than U2, and significantly so on bulkheads and exit rows. I have measured it on over 20 aircraft. Leg room is about the same.
