  The first thing to note is that 9...Na5 and 9...Be6 can transpose if white replies to each with 10. Bc2. Before playing 9...Be6 you should decide how happy/comfortable you would be if white chooses to exchange with 10. BxB. If you prefer to keep pieces on the board or dislike the change in pawn structure then choose one of the other moves, maybe go with 9...Na5.
  
  The moves 9...Na5, 9...Nb8 , 9...Bb7 and 9...Be6 are all played with different ideas in mind. Although they are all evaluated similarly by engines they can lead to very different positions. Which one you choose should be decided by how comfortable you feel in the types of position which result, how familiar you are with those positions and to a lesser extent how familiar/comfortable you believe your opponent is.
