Yes, growing conditions are certainly most important. Old growth had particular growing conditions - a very high and dense canopy for once. Species is also more important FWIW! If you're making a window you should get a rot resistant species, not old growth stuff. The point in OP is that if you find old growth stuff, hey, try to keep it because it's probably really good wood.
