Both.
I saw Platoon as a kid... came to see Apocalypse Now! in my early twenties.
I like the more conventional, classic, epic, realistic, romantic portraiting of the Vietnam war in Platoon; it's like oneself had went there and lived the situations that very likely had to take place, seen through the eyes of the rookie Chris Taylor (Charlie Sheen): an incompetent lieutenant, the divising factions in the platoon around two very opposite natural leaders: Elias and Barnes; having to make a decision in which to belong (with survival at stake). The music is sublime and, imho, captures marvelously the high drama of war, the sadness and meanness of ultimate treason... also, the great scene at the end, at the battlefield, when Taylor, hardened by his experience and stating his views, takes his resolution. Also it brings memories to me of when I used to see Tour of Duty on tv, with that echoing guitar at the end and the soldiers marching in the sunset...
If I had to choose, it would almost be Platoon by a hair but I take both quite happily
