I am a deaf guy and if I was ever to have a child, I want them to be hearing.
You can talk until you're blue in the face, but if you're deaf, there are just SO many lost opportunity that you will never be able to do and there will be some difficult in life that wouldn't happen if you could hear.
I'm Hoh/Deaf ... I don't think I have many "lost opportunities" because of it. I've played musical instruments (casually and professionally).
I've played on sports teams (volleyball).
I was in advanced placement classes in elementary school through High School & graduated High School will honours.
I went to college in a different country when I was 18 and graduated with a GPA of 3.94 (or 3.98, I can't remember it was 15+years ago).
I worked in a very specialized (male dominated) job and had clients from all over Canada who sent work specifically to me.
I was in a car accident in 2004 that forced me to stop working. After my health stabilized a bit I went back to school - to university, locally this time - and studied theology for 2 years (with ASL interpreters), and worked as a volunteer/lay leader in many churches etc.Unfortunately in "year 2" of university, my medical condition worsened and I was diagnosed with Fibromyalgia,Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), Osteoarthritis and a number of other things - so I took a break from school to take care of myself.
I can honestly tell you that being Hoh/Deaf is NOTHING compared to living in Chronic severe pain.
Being Deaf to me (and most other Hoh/Deaf people I know in real life) is like being female vs male, blonde vs brunette, short vs tall, black vs white .... is it "easier" to be a hearing, male, brunette who's tall - YES... does that mean it's "better" - NO.
While I wouldn't genetically engineer a deaf child - I'd be completely happy/content if I naturally had a child who happens to be Hoh/Deaf.
If I was to adopt a child, I'd likely look for a Hoh/Deaf child first because as someone who's Hoh/Deaf myself, I understand what it's like to be Hoh/Deaf in a way that hearing people cannot. I also understand the communication needs, literacy needs, and access needs of someone who's Hoh/Deaf - and will be an excellent advocate for that child, as well as someone who can teach them how to advocate for themselves.
