Adult Sasuke wins. The dimension teleportation is a very interesting ability. His powers have definitely improved beyond measure, simply on the basis of large reserves alone as Dimension swapping is very taxing for Kaguya as well. I don't know how he manages it, but his reserves are something else now.
If not anything else, then he should be able to swap Vote Sasuke with himself against Indra's arrow. It is not like he hasn't done teleporation and swapping before; Kaguya and PS in container form. Or evade it outright by simple teleportation in any direction. Vote II Sasuke is done after that. It's a shameful stomp match.
P.S: Interesting arguments in this thread and some nice group versus group trouble and the nauseating debater-wankery from certain members. Anyhow, altering any Susano'o's form doesn't power up its localized factors (speed, strength, durability) in any way, as it's ninjutsu. Unless any chakra doesn't go through the user himself, there is no powering up PS or if the chakra is not shown to be directly drawn upon; as in case of the chakra filling up that container PS powering up Indra's arrow or presumably the senbon.
Sasuke's last PS was still PS. There will be no change in its durability, speed and physical attack power or even other attacks unless it doesn't directly pull on the exposed Bijuu Chakra. He simply rearranged the available chakra space to form a new form that would be accommodating for the chakra. Otherwise, as PS only has limited chakra, a large chunk of its portions were completely empty. You cannot make anything better than PS.
