Majority. Parent said majority

Exactly. Use after free is common enough that you can't just assert that out-of-bounds is the majority without evidence.

actually you may be right, according to project zero by google [1], ~50% is use after free and only ~20% for out of bounds errors, however, this is for errors that resulted in major exploits, i'm not sure what the overall data is
