Shaw all day. Luke is seeing his father, it’s jarring to have him look younger than Luke himself, jarring that Anakin doesn’t match the ghosts he’s with (clearly the age they were at their death), jarring that Hayden looks pasted into 20 year old footage, and jarring that Hayden kind of sinister in general.
Like most SE changes, it’s more distracting and pointless than it is worth.
