I think it's hard to say. Grok is pretty good and also fairly free with good usage limits.

Every single AI company in my opinion is committing fairly grave misdeeds with the ruthless scraping of the internet and lack of oversight.

Not to mention the shady backdoor deals going on with big tech and the current administration.

Grok is also pretty bad with its whole gas turbines in one state and datacenter in another and some possible environmental issues

It's more of a pick your poison at this point
