If your getting destiny and all the dlc, it will be cheaper to get the legendary edition (includes everything in one package).
As for the question, I'm curious if you plan on getting black ops with its dlc. DLC for black ops 3 will significantly expand the zombies portion, but if you are in it for just the multiplayer, then it's basically just more maps/skins
Utimately, I would pick BO3. It simply has a lot of interesting components (story, multiplayer, zombies) and you can enter without feeling behind
