Many. For me the biggest one is code readability. I am very, very happy with their choice of NASM syntax. The idea behind intrinsics is that you use one, or several assembly instructions in your code base, letting the compiler manage registers for you. But (especially these days) there is rarely a single instruction that makes your code go faster: you have to write entire large blocks of assembly. That is much better done using assembly than intrinsics.
