There is no "best" race or army in either Warhammer or Warhammer 40,000. They are all equally balanced so that players will not choose them based off of which is simply the strongest, but by which one best fits their playstyle as each army has a very distinct way of fighting and everybody is sure to find at least one that fits them.
There is none! It depends on your stratagy and your tactics!
If you are serious about Warhammer 40K you can only play Orks.
In warhammer terms TAU is a young yet sophisticated army which includes kroots and fire units. Personally I believe Tau are the best with Eldar in warhammer 40k.
THE first Warhammer fantasy army that is still used is Lizardmen. they have some of the best magic and their troops are totally pimp.
