javascript carousels: change position or scroll offset?

While there are a ton of jQuery carousel plugins out there, I like to roll my own.

Reading through their code I've noticed that people manipulate either scrollLeft or position (left: -100px) in order to "move" the carousel.

Which one is b开发者_运维问答etter? Are there any performance benefits from one or the other?
