Is IB a good prep for MIT?

I have kids who went the IB and the AP route. My experience is that the IB route is way more time consuming and broader. It is also a lot less flexible if you are a math/science type. Doing AP allows you go a lot deeper into those subjects at the expense of the humanities.
My kid who went the IB route had a difficult time balancing it with the demands of a time-intensive varsity sport.
Both routes are good but if you want to go deeper into the sciences I would lean towards AP.
