I have a feeling to the average user there isn't a major difference between the major LLM chatbots. They've all converged on pretty damn good. Even more fringe ones like Grok.

What I'm interested in is who gets the most integration. Google has Android and Search so they have a big advantage and they seem to be the first to roll out a Home voice assistants (early release started in Oct). Beating out Alexa and Apple home.

iPhone is still missing a proper Siri but they will still have control of multiple huge platforms.

xAI / Grok is stuck in the fringes a bit. Maybe they'll focus on APIs and affordable business stuff, or some social media play.

Anthropic seems to dominate in coding and API stuff as well.
