In languages that don't hide much (e.g heap allocations in Java), less complexity corresponds to better performance (up to a point). Because better performance is fundamentally about letting the computer do less work. When pointer indirection is explicit, the programmer is nudged towards thinking whether they actually want it. Same with dynamic dispatch, polymorphism and every other runtime complexity.
