Based on each character's strengths and weaknesses, who would make the better soldier, Cassius or Brutus?Julius Caesar by William Shakespeare

While he is flawed in that his love for Brutus prevents
his better judgment at times, that Cassius would be the better warrior and strategist if
his counsels were not disputed is evinced throughout Shakespeare's play Julius
Caesar.

• Cassius is, as Ceasar himself
  remarks, "lean and hungry," qualties that motive men to conquer, which is the goal of
  all soldiers.


• Initially, he does not believe in fate, as
  does Brutus.


• Cassius is cautious and mistrustful of men. 
  He immediately questions Marc Antony, Caesar's friend, about his motives in making an
  agreement with him and the conspirators.


• Cassius
  understands that conquerors eliminate their enemies; therefore, he suggests killing Marc
  Antony along with Caesar:

 I think it is not meet
Mark Antony,
so well beloved of Caesar,
Should outlive Caesar. We shall find of him

A shrewd contriver; and you know his means,
If he improve them,
may well stretch so far
As to annoy us all, which to prevent,
Let
Antony and Caesar fall together.
(2.1.163-169)

• After
  the assasination of Caesar, he counsels the noble-minded Brutus to not allow Marc Antony
  to speak before the Roman people because Antony may stir the crowd against
  them.


• He realizes the importance of being decisive and
  urges Brutus to act quickly on things.


• In Act V, he
  suggests that his and Brutus's troops wait at Sardis and make the enemy forces march to
  them, thus tiring the enemy rather than their troops.  Then, their troops can be rested
  and battle-ready.  But, Brutus refuses to do this, and this decision if fatal.  At the
  end of the play, Cassius also falls prey to superstition, but, again, he seems
  influenced by his friend Brutus, who is greatly flawed in his commitment to principle
  over practicality.
