There’s significantly less plastic in them, they only have to have a very thin coating to prevent the metal from oxidizing, vs having to be structurally supportive and retain its own shape. On top of that, aluminum is infinitely recyclable
Yeah, I think the recyclability is the main thing: plastic bottles cannot be recycled into the same grade of plastic in most cases, whereas aluminium cans can be recycled back into more cans.
The last point is always funny to me, because cans are plastic bottles inside of aluminum bottles. There is less plastic at least, I guess.
