This one's a tough one. Would I rather be unable to hear or see? I can't really know because I have no idea what it's really like to be either way. I can only imagine it simplistically. Especially for people who've never known what it is like it's very interesting to try to learn what they even think about the senses they cannot experience - but also impossible to ever truly know what it's like.
Maybe it's best to look at the infrastructure available. And I think just by the nature of it, there are more ways to imitate the knowledge we take in through audio cues with our other senses than we can with visual cues. We can converse through written word or sign language. On a purely informational basis, a lot of sound can be transformed. Still, the experience, I think, would be a big loss. To replace vision mostly the sense of touch is leaned upon, and people use it to overcome challenges in amazing ways. Maybe because it seems we are always looking at things but a lot of the time not really listening to the white noise around us, vision still seems like a much harder thing to replace. So I think I would go without hearing if I had to, but as I said I cannot know the experiences of either and what they entail.
