Live, the User interface is awesome, and the amount of aircraft. X plane mobile has way way better cockpits and better physics on their aircraft. But there UI is atrocious and the multiplayer is boring.
Infinite flight has a good amount of planes and airports, and a very usable and customization interface. Both X plane and Aerofly have less scenery and planes
I don’t see how quality of aircraft has so much votes sure good outside textures on around half of planes but on Aerofloy quality is consistent and high detail on planes. of course I do think infinite flight is better all round :)
