Can’t speak for Casey’s stuff but I’ve had the other two. Tom has put a lot of work into his and there is short term value in his program but PTSG is on another level. It’s been around longer and has many people producing content. You can’t get through all the videos. I’ve also tried Max Michels program and found it to be excellent. Additionally, I tried Steve Andersons online program. It was in its infancy but I found it to be quite mobile unfriendly and didn’t find the value in it.
