It all depends on how much more power you have than your opponents. If you're one of those whales that out powers his opponents by 50k, get Hiruzen. If you're generally at about the same power as your opponents, your Hiruzen isn't gonna hit very hard. Most of the people you'll meet will have shields, root or Minato's buff. Hiruzen has a hard time doing damage to similar power players with the aforementioned buffs. If this is the case, then Madara is a better choice. You can run the water main chaos cancer, or use him with Jonin Minato.
