People here tend to hate on Musk, so hence they hate on Grok, but here is for the grown ups interested in a concise comparison.
I also prefer and use Gemini more than Grok overall, but when I really want to go into some conversational rabbit hole, Grok is my choice.
Btw, Grok offers a FREE Imagine(video creation and image to video) function right now!
It used to suck terribly but the latest version is dramatically improved and almost as good as Veo/Sora.
