IB vs City College?

Hi there! I know many kids who are “dropping out of high school” at 11th grade and going directly to college for two years, and then university… I also know many kids who are taking the IB program, and getting their IB diplomas. I just wanted to ask which one looks better on a university application? Because going to college at 16-17 years old is impressive, but taking the IB program is also impressive as it’s pretty much taking all APs if you’re doing full IB. I don’t know though? It might be a lot of big talk. Please let me know which looks the best on a university application – going to college instead of completing high school or completing the IB program?

Thank you.
