What is the best AI tool for software development? Discuss?

I was googling today (tabnine vs chatgpt) and found this half-baked article but surprisingly it's the no-1 article on Google so thought to discuss this topic with you all people.

1- ChatGPT 2- Copilot 3- Tabnine

or any other contender in the market which you would like to highlight and discuss the benefits and why it's better then above top 3
