Assuming that the sexual function may still be there either way, I'm going for the penis that will let me pee standing.
If I'm going to get surgery, you can bet my willy that I would want to be able to pee standing up. If I wanted a penis with "visual appeal" that won't let me pee standing, then I can just get a non-stp packer.
Not all biological penises look visual appealing. Plus, I'm not the type of person to take a public shower if I can avoid it. I'm not going to drop my towel and say "Hi I'm Malachite, LOOK AT MY SCHLONG! LOOK AT IT! Have a nice day!". Other than the doctor, I will pretty much be the only person seeing it.
If the visual appearance REALLY got to me then I can just get a revision.
Seriously though, if it doesn't have erongenous sensation than neither for me.
