Hero
A bit of a mix. I design my adventures based on party composition, same with loot. However I tend to skew loot towards player preference of type of items. If a player is primarily melee with a focus in rapiers I try to make sure they get good options for rapiers, either as a drop or for purchase, but don't cater to their desires completely. I will also try and remind my players of options they have available if they seem to be lacking healing/scrolls/etc. Other than that I generally leave the logistics to the players.
