no real difference between those two, on arrival at T5 follow the purple signs for flight connections T234, get the airside T3 bus, on arrival at T3 go through connection security and then you are in the departures area.
if arriving on an international you may arrive at the satellites T5B or T5C, and you can pick up the bus from T5B rather than head all the way to T5A.
