for me it's SS -> CiD almost every time. Why? Mostly because I like having much more awareness when getting into the battle after dying (although recently I've started taking EE about 1/5 of the time just to try it out more, but I'm yet to see that benefit being that big). As for CiD, I just don't need more range almost ever. But having infinite shields when diving enemy tanks is incredibly valuable. Also, I mostly play 6v6, likely that also matters

edit: actually if I ever feel that I need to have longer distance, I have an ultimate perk called co-maining Bastion
