does the seat count make a difference?

hi... if you chose to use premium Y seats, your flight get's a higher quality and thus it could bring you more passengers... now... does the count of the seats make a difference too? so, are 130Y vs. 150Y seats (same seats) also more prefered by the passengers, or does this not make any difference?? ... and by the way, these quality factors... how much do the count at all when calculating the preference of passengers?
