Each of the Ai's are good for different things I find, grok I find is generally only useful for stuff like "which cpu should I get, my use case is xyz" because it does a decent job of looking stuff up and comparing numbers (It's also decent at looking up historical data), but they all have the same issue imo that they dont provide any sources for where they are getting the information (or if they do the pages they link to are always a 404) from and if you ask 3 AI's the same question you'll normally end up with 3 different answers. But grok is just twitters AI (like chat gpt, gemini (googles ai) or deep seek). People are far too quick to take what AI tells them as fact though, personally I find the infomation they give is wrong pretty frequently or it's biased to specific answers (which is going to get worse when companies start paying to have their products and services recommended).
