FS ACARS is much better in my opinion as it had at least two advantages over FSP. It will be free to use for pilots. I've seen the software and it looked very convincing but not all of us can invest in new softwares. It will not require adding new softwares to my currently overwhelmed pc! ACARS will be developed for the airlines and can be expanded (at some point in the future) to included cool things like flight, weather, fuel planning etc. I've used many ACARS over the years with differnet airlines and even though it might not be as flash as FSP ACARS wins hand down for me!! cheers all
