Do you agree it’s like the “s” in vision?

Digraph “rz”

Like the “s” in vision, or fairly similar Zhivago. Sounds exactly the same as ż. Even Poles find it impossible to pronounce after “k”, “ch”, “p”, or “t”. Pronouncing it as “sh” is fine in those cases. the only difference being that “ż” evolved from a /*g/ while “rz” is descended from a palatalized ar /*rʲ/.
