Can someone tell me what makes people think Grok is superior to ChatGPT?

I am honestly curious what benefit Grok 4 gives aside from being really good at coding and having great access to live info due to X. I use ChatGPT for creative type work, generative AI(images and video), research on products and subjects i am interested in, learning new things, etc. I dont do any coding, I am just curious what is so amazing about Grok to think it is so much better? And some say the Voice Mode is better, better how? What does $30 SuperGrok get me that ChatGPT Plus doesnt?
