Each purchase adds to the story that's been set up. They also allow better odds of getting gear specific to each add-on (Ex. Comleting The Dark Below story missions awards you Murmur). With the new quest system though, some quests and ativities may have to be completed in a certain order to unlock another (Ex. A Broken Will will lead to A Sword Reforged). If the lore in the story matters to you, I'd advise you to go in order the add-ons were made available (Dark Below, House of Wolves, Taken King, if you don't know). If you want to level up fast and get the best gear, go for the Taken King related content. Most gear that isn't exotic from the first two add-ons is weaker because they have lower attack and defense limits. But you may want to do some of the older missions too. They may help you get more experience faster if you're not at max level already. What you need to do depends on what you want to do. If you know that, it should be easy to figure out where to go.
