Pick Grok for one reason above all: Real-time access to X posts makes it strong on breaking news and trends. Pick Microsoft Copilot instead if this matters more: Deeply embedded in Word, Excel, PowerPoint, Outlook, and Teams. Both are freemium, so price is unlikely to decide it. The trade-offs are real on both sides, so weigh Grok's limits against Microsoft Copilot's before committing.
