Five weapons, five bulkheads, which armor is the best?

Just popping in to clarify armour/bulkheads/etc, it seems there's still a lot of confusion on this point! Probably the best way is to illustrate it with an example (note that the numbers are pulled out of the air, I'm writing from home and don't have access to the real ones, nor can I check if I'm allowed to post em ).

Trying to figure out which bulkhead protects best against collisions.
