Very True flying for fun
I am only suggesting this as I too investigated practically every groundschool FTO in person and after considerable thought and investigation I chose ATA. As seen before on this website it really will depend on which suits your own personal situation, call them all and visit them all and it should become evident which suits you best. I certainly would not suggest making your final decision until further investigation but I did feel you should at least include them in your selection as you never mentioned them in your choices.
