Which style do you prefer?
I prefer being hassled at random times by fare inspectors and forced to pay penalty fares if I'm not quick enough to produce a ticket.
I prefer queuing up to enter and exit the station, dealing with balky equipment, and using hard-to-understand fare structures.
I think public transit is the Devil and all right-thinking people have private means of transportation.
My city uses something even worse than the above options.
(FWIW, Vancouver buses *do* require that the transfer ticket or day pass be checked, and that you keep it with you... which seems the worst of both worlds.)
