Your question really can't be given one straight answer. Dr.s vary in their skill at working with nerves, defining a glans from the shaft of the penis as well as some other things.
Nerves have a better chance of regenerating and healing in younger people than in older people. (teens as opposed to thirties). Since i had mine so long ago, I've looked at sites to see what the results from phalloplasties are these days. Some are very good, some look like mine. The first procedures were dropping a flap from the abdomen. After that came the radial forarm flap and now there are flaps taken from the thigh and one Dr. takes the flap from the side of the body and includes some of the muscle.
Most Dr. try to incorporate or at least leave on the clitoris. That way, if there is no erotic feeling in the new phallus, the patient can still climax. Its hard to predict whether a nerve hookup will work. Even if the procedure is the same. I don't think you will find a Dr. who will gaurantee that you will have erotic feeling in the penis. There are implants that allow for an erection, but it won't be the same as a cis man's erection.
One thing I can say, mine is just a hollow skin tube with no feeling or definition, but I have never once regretted having it done. It comes down to how important it is for you to have something between your legs that is not a prosthesis. For some its important, for others its not. One doesn't make you any less a man than the other.
