Also, go to the Compiler Explorer and compare the generated code for C++ "num / 2" when num is an int, and when num is an unsigned int. While there are a few cases where the compiler tends to do a better job of optimizing signed ints than unsigned ints (generally by exploiting the fact that signed integer overflow is undefined), they are not as fundamental as "num / 2". Being forced to write "num >> 1" all over the place whenever I care about performance is basically a dealbreaker for me in many projects; and I haven't even gotten into the additional safety issues introduced by undefined overflow.
