It really depends.

That extra movement speed is more helpful against lanes that have skill shots and it helps when you need to get around more. That slow will also help ganks by keeping your target from running away, but that slow won't help as much if the AD carry has dashes/blinks. (Ex. Ezreal, Caitlyn)

If you feel like your AD carry is getting poked too much then maxing the shield first will help prevent a lot of the damage. Of course this assumes you're quick enough to shield the AD carry before he/she gets hit. Also that sheild is more helpful if your AD carry does want to be aggressive and has burst (Graves comes to mind). An extra 30+ ad in the early game is big.
