On the Java Edition the scream that calls the warden is more frightening and terrifying, on the Bedrock Edition they are not very fearful.
Try running a shrieker a couple of times on the Java and a couple of times on the Bedrock. There is a big difference
Can confirm in 1.19.51
the sounds of the sculk shrieker are the same in each version, but in bedrock edition the screams are quieter and can only be heard 16 blocks away. The upcoming 1.19.60 version is going to increase the distance of the sculk shrieker's sound to 32 blocks and make them louder which is reported as MCPE-163989
