If you prefer more of an Arcade style with no stress then I think World Of Tanks is for you, but of course War Thunder has more realism like the spots where you can penetrate certain vehicles. In War Thunder you can either play Arcade battles or Realistic Battles where the difference is that in RB (Realistic Battles) you can't see the enemies easily. Overall it's up to you to decide which game you like. For me War Thunder is a winner.
