AI assistants are everywhere in 2025.
They’re writing emails, planning your week, summarizing meetings, helping you code, and even telling bedtime stories to your kids. But here’s the big question:
Which AI assistant is actually the best?
I’ve spent the past few months testing ChatGPT (GPT-4o), Google Gemini (Pro 1.5), and Claude 3 (Opus & Sonnet) in my day-to-day workflow as a digital marketer and content creator.

Each tool shines in its own way—but ChatGPT (GPT-4o) consistently delivers the best mix of creativity, usability, and speed for most tasks.
Claude feels the most “thoughtful” and safe. Gemini integrates best with Google services. But for versatility, ChatGPT is still my go-to.
