The tradeoff is control vs speed/efficiency. Generally, I agree with you (and prefer to just rely on my own function library), but for the most part this is for somewhat dogmatic reasons like "you know every character of code..." etc. While those things may be true, they don't necessarily make my code any more secure, bug-free, or well-written. Recognize that any popular framework has had a lot of eyes on it and any pain/problems with it will have been fixed. The idea that you know every character of code and therefor have more "control", is not entirely accurate and probably misses the point.
