Depends on the types. List.first([]) will return nil but hd([]) will throw an error, and Enum.count(...) works on any enumerable and length/1 only works on lists (byte_size or bit_size for binaries and map_size for maps). Plus hd/length work in guards where the others do not.
But I use the type-specific forms when at all possible to help ensure proper types.
