Which raises the key question of just what the heck you mean by "the plot".
Adventure Paths are well-known for having a single over-arching plot. One major world event is unfolding. Other things going on are minor distractions at best. Instead of the focus being on world or site exploration, the focus turns to exploring this one key plot. Just like discovering new areas in the WLD or exploring Giant Land, the players discover more about the plot as they push towards its finale. Players that have bought into a plot-driven game are less likely to explore the Spooky Castle because it exists unless they discover or suspect that it is somehow tied into the plot.
I've enjoyed games both ways. And it is helpful to understand what method your players lean towards or are currently leaning towards. My wife only likes plot driven games (she only starting playing this decade if that helps any gaming historians). My main group likes to mix it up, so we have no trouble playing some WLD and exploring the site freely or hunkering into a Paizo Adventure Path leading to a showdown with Kyuss.
