For me, neither cards are really comparable...apart from, of course, being swords.
The two relates to the High Priestess: The Prime Feminine number. Our awareness of our existence and therefore, the beginning of intellect as opposed to ego.
It is a card of the subconscious represented by the water and the moon. The swords are pointing in an upward direction, the apex downward representing the symbol for water - Reflection, receptivity and the subconscious.
The figure wears a white robe, purity, wisdom, the divine against a green sky: healing, immaturity, promise and inexperience but also fertility and growth.
The figure is blindfolded which can represent blindess to materialism and inner vision.
But how long can this person maintain this position without becomming weary? How long can they maintain their blindness at the expense of the outer, the conscious?
The sea is this persons potential but they are blind to it, have their back turned to it. They are consciously holding up the swords, the swords can be lowered and the blindfold taken off. What are they refusing to face? How long can this position, this stalemate continue? What are they ignoring and refusing to see? It's there if they choose to look and their position cannot be maintained indefinately or defiantly.
The eight relates to Strength. Eight is the intermediary between terrestrial order (the square) and eternal order (the circle). Associated with the Serpents of the Caduceus, with infinity, with the balancing of forces or with the equilibrium of different forms of power. It is a number associated with regeneration, strength and inspiration.
The female is again, the subconscious mind but here the water is in tiny pools, a returning tide will come to drown her. The subconscious is bound with cord. There are more swords on the left hand side of the body. The left being primarily the feminine, the subconscious, receptivity and the past.
Her potential seems lost, there is little water beneath her. She seems trapped on all sides. This time the swords are wedged into the ground, grounding their potential, upright meanings.
She isn't struggling, does she really understand how that tide may rush in and enpower her? Why doesn't she try to find a way to escape her bonds? Maybe she is afraid of getting entangled further? Of falling over and hurting herself? She could be unsure of which way to go and needs guidance. She could be choosing to remain inactive until she figures out what to do or is forced into action by the incoming tide.
Not only is she bound but blind as well. Unlike the two of swords who can lower the swords at any time, she has a further obstacles, her body is restricted and swords surround her. There is a path forward but she is unable to see and unable to take off the blindfold. She feels restricted by things beyond her control and powerless to free herself. She is blind to the freedom in front her her. She need only take a few steps to get free of this vicious circle.
The red of her robe, can represent willpower, life force, passion, desire, courage and action. They are all present but bound, she has to find a way to get them free. For the moment she can't see it but she must be assured she still has them.
