They both are great Sims.But they are Night and Day,The Shark is more of your low level tree skimming hide behind the building pop-up from behind a hill type of buzz in your shorts kind of Sim,And the A10 well thats a whole new ball game, Its unlike anything you have flown in the past..Cus not all warting is done down low. Its not your daddys old A10 where if you broke agl's 3 you where too high.The sys,wpns and the flight model will let you fly the A10 like never before. I would get the A10 and when the A10/BS patch comes out grab the Shark and have to best of both worlds...lol just my take on it.:pilotfly:
