Moves are usually pretty cheap/fast. With a container like std::vector it usually just has to swap a couple pointers and sizes regardless of how many elements are contained. Just do what makes the code simpler for now. If you encounter performance issues, you can use a profiler to identify the actual bottlenecks.
