Sheik or Lucario for main?

[Hungerr]

I know both are top tier material, but im new to the game, and im wondering wich of these 2 should i choose as main?

Im overall new to the smash series and i just cant decide wich one should i practice. Wich one is easier to master?

Lucario, rage effect+aura effect, the counter is pretty awesome to use, though Lucario's moves have big delay, you can still KO almost anyone when your at 120% and the opponent is at 60% with a big attack.
