Until a few years ago (here in Australia) it was callsign and then readback.
I preferred it. The reason?
When the readback is being received, the ATCO is concurrently electronically notating the correct readback items - and THEN gets the wrong callsign at the end. Hopefully hearing that correctly and undoing, fixing and repeating instruction. If the callsign was first this would be picked up straight away.
