The evidence suggests that acceptance rates at many colleges is higher for IB diploma candidates than non-IB diploma candidates–for some, much higher.
The best evidence, unfortunately, is about ten years old and so is a bit out of date, but we can still use it to draw inferences. Even though admissions rates have changed pretty drastically since then, I go under the assumption that the same level of preference (or not) still exists, just scaled down a to match the current overall admissions rate.
Anyway, this was revealed in a student-reported survey around 2008 or so. It has almost competely disappeared from the internet, but I found it in one place.

My recommendation is to skim through the list for the schools you’re interested in, and then decide if it is worth it.
(Incidentally, my daughter was forced to repeat Calc I as a result of entering IB, to let the rest of the students catch up to her (she had been a year ahead in math up to then). We thought it was still worth it. You need every single tiny advantage you can find in the current admissions environment, but the important thing is doing well and not getting overwhelmed). Best of luck.
