We have to be more precise about what shall be counted.
1) Positional judgement during the game: Various methods can be applied. Some count great numbers, others count small numbers. For some the "great" numbers are just a few points greater than the "small" numbers (like local endgame counts including a few newly played boundary stones but disregarding prisoners). Area and territory scoring are very similar in positional judgement because counting methods for either can be adopted or modified to be adopted. The difference between counting or ignoring eye points in asymmetrical sekis or 1-sided dame is tiny.
2) Counting the score at the game end: Both area and territory scoring allow various different counting methods including such where counting is not even necessary but only the winning player's winning margin is seen (subject to komi). E.g., fill in empty territory intersections pairwise until one player's intersections are all filled. E.g., fill all, then remove pairs of one black and one white stone. E.g., fill all, then arrange all stones tengen-symmetrically as far as possible. You do not need Ing boxes for that. Both area and territory scoring can be reduced to seeing only the winning margin. (Hence one should compare elementary counting steps including actions like moving, removing or filling a stone. Both scoring systems have equally fast such methods, provided the life, death, territory status assessment step of territory scoring is pretended to consume 0 time.)
