The one who’s not thick.
Think about it. The application lists senior courses, so rigor is already known. The transcript has 3 years of grades through junior year; how much different is Q1 going to be? No AO is going to say, “Oooooh, the kid improved from 3.93 to 3.96. Admit!!!” Nor is the AO going to assume that the Q1 transcript not sent contains C’s.
Nobody ever said life was fair
