People say Google has a search foundation, so Gemini search is strong. But in my day-to-day use, I’ve found Grok to be much more reliable. For the same question, “Will OpenAI Codex support Skills soon?”, Gemini completely failed, while Grok searched 10 web pages and 9 X posts and answered accurately.
For content that is extremely time-sensitive and relatively niche (like technical topics), Grok has data from X to help with judgment, not just web pages. This may be why it always meets my search needs.
