I have personally attended and received ratings from both ATP and AF. ATP had a better organized program and was much quicker to get ratings but my instructor was absolutely awful. At AF on the other hand, my instructor was awesome but the program and school itself was horrible and burned me. Both are extremely expensive and I have to agree with squawk, and to look for more options. If I absolutely had to do it all over again and only had those two choices I would go with ATP and their career airline program strictly for the value of the multi time and the layout of the program and I would request a new instructor if I had the same one I had before. Good Luck
