I think the character of Myra had, if anything, a bit more depth, a bit more light and shade to her. She was more of a pragmatist.
She also had one of the best exits of any character in the serial, bowing out in the fantastic terrorist seige episodes and dying a hero.
Although paradoxically, killing Myra off at that time was probably just about the biggest mistake the producers ever made IMO and Maggie K had to pretty much carry the show single handedly thereafter.
None of which detracts from the character of Bea of course who was great too (and the original top dog of Wentworth) and some super performances from Val Lehman as well
