I too struggled with this very issue and in the end decided for shallow depth. I am 11 weeks post op. I certainly have zero regrets at this early point. I do not feel in the least bit "artificial." As I shared in another post, I recently found myself naked with other women in a pool changing room and felt completely whole and accepted. The depth of my vagina never crossed my mind!
I have a lifetime female partner, so penetrative sex is irrelevant. However, she is 10 years older than me and has some aging issues. Who can tell the future, someday I might be interested in a man? Actually, for most GG's, the best sex is clitoral organism and not vaginal. I have a clitoris.
So even though I have been spared the worst complications from a full depth procedure, I have had minor complications and a very challenging recovery. GRS is a difficult surgery, regardless of the depth. I am spared the need to dilate, I have to be devoted to the care of my SO at this stage in her life. I hope this helps, but please be at peace with whatever you decide. You will need all your psychological strength for recovery.
