Sorry but no. D&D 5e is the poster-child for a dumbed-down, over-simplified and superficial character creation system. Even just within D&D, 3.5e is far more deep, complex and sophisticated, as amply demonstrated by the awesomeness of character creation and development in the Pathfinder games. But even better as a deep and complex system is that of the PoE games, which for me is by far the best out there.
I know your take here is popular in some circles, but I personally don't think 3.5 was deep. It was complicated and bloated... but not deep. IMO 5e is the better system because it is simpler, and gets itself out of the way of playing the game.
I love the 3.5e derived pathfinder games from Owlcat, but they are great in spite of the system, not because of it.
