Are cis vaginas different?
Ok. I present only my own information and mileage may vary, but all vaginas will stretch. Cis women have a uterus which during high arousal will move out of the way, or so one sexologist said.
Again, in my own experience and with dilating as often as the surgeon required post-op, 39 years later I still have depth and what I found was the vagina is adaptable and will adjust itself. Depth can be recovered, though it has to be done incrementally.
Not sure about scars. I don't see any, but I'm a Biber alumna and I am only speaking to that.
Finally, most men aren't the ones from magazines no more than every man's build is like Arnold or a Fabio or whoever it is these days. And yes, I know, muscles and penis size are not a one-to-one correlation.
This post is one data point, but I felt I needed to add it to a somewhat "downer" view of things being put forward.
