Witness Reverend Jeff Hood told reporters he saw a man ‘struggling for their life’ for 22 minutes as Smith became the first US death row inmate executed by nitrogen asphyxia

Humans LONG before you had the debate already. Pick up a history book, please! You are not a unique snowflake with concepts this earth has never before thought about. Everything that rattles around in the paint-can on your neck has been debated for generations.
If it is a public debate it'll be in the news. Private debates are like this. They may show up somewhere on the internet but nobody cares and it isn't represented in the public consciousness.
I read about 50 books per year, one a week. Nothing sticks out as one leading a public debate on this question. Most published books aren't read by more than a few hundred people. Is there one you are thinking of that I missed?
