Depends on the college and what their suggested HS preparation is. For those colleges at the Ivy tier that suggest 4 years of a FL, 2 will be uncompetitive. These colleges are not looking for specialists in HS.
Additionally, most of these colleges have FL graduation requirements, so in theory, the more FL you take in HS, the less you need to take in college, which frees up your college schedule for real CS courses, as opposed to APCSP.
Plus taking APCSP after having completed APCSA is like taking Algebra I after precalc.
