Which high school is better for a college-bound academic student: City High or GR Christian High? or other else?

Hi everyone, My child is quite academically inclined and hopes to get into a top university in the future. We’re currently trying to decide between City High and Grand Rapids Christian High.

Does anyone have experience with either school, especially in terms of academic rigor, college prep, and overall environment for a motivated student? Any insights would be greatly appreciated.

Thanks in advance for your help!
