Grok Bot vs OpenAI Dots. Which one would you choose?

I've been thinking about trying an AI agent that can handle more tasks independently instead of just answering questions. I'm a little confused between Grok Bot and OpenAI Dots. Both seem interesting, but I'd rather hear from people who have actually used them. Which one would you recommend, and how has your experience been so far? Would love to hear the pros and cons before deciding which one to try!
