IB Diploma Program vs AP?

This year I'm a freshman and just taking the "pre-IB" cles. I decided to take the IB Diploma Program cause the counselor made it sound really great and like I could get into any college I wanted if I took it. Started researching and found out IB vs AP at colleges doesn't really change much except you get less credits with IB. I've never had to study longer than 15 minutes for any cl, this year I haven't had more than an hour of homework (or ever really), and I have straight A's in all my cles (advanced/honors). I'm worried if I take IB it'll be a huge shock and I'll have to do hours of homework once I hit 11th grade. I'd really rather ease into it. My question is, if I take AP would it prepare me enough for college and is it worth it to switch? Or should I just stick with IB? I know what college I want to go to and you only get credit/exemption if you get a 6-7 on IB HL tests, so to me it makes more sense to take AP if I can get the close to the same level of education, a little less work, and more college credits. What do you guys think?
