Depends a bit on preference ofc. Personally I think the deathmantle looks a bit more rogue lore wise (more visually unnoticable and shadowy) but I like the red of the season 2 as well. Overall I don't like the sets however (kinda distaste the 'I am skeletor from He-man' mask, and also the shoulders)
But if I had to choose between the 2, i'd chose the season 2 set.
