There is on subistute for stick time....no a sim is no match for an instructor.....An instructor teaches you so much more than how to fly....safety and field manners are 2 things that come to mind.....
A student with a sim will progress faster than one with out a sim there is little doubt...but I've never seen a sim land correctly...close but not quite...besides the pucker factor increases when you can't hit the reset button and start over.......
fly the sim but get with an instructor use the best of both and solo faster......good luck
