IB vs AP classes

I want to go to California colleges for both my minor and major and also veterinary school. I’m in my 9th grade year this year and I have two options. That is wether to take IB or AP classes (I can’t take both). What would California Colleges prefer?
Thank you!

You can take a look at their AP and IB credit listings to see which ones are better accepted for subject credit and advanced placement (but also note that some professional schools may not accept AP or IB credit for their requirements).
