Which AI Coding Assistant Should I Invest In? 🤔 (ChatGPT Pro vs. Claude Pro vs. Gemini)

Hi everyone! I’m currently at a point where I want to subscribe to a premium AI assistant to speed up my development workflow. As a Full-stack Developer, I do a lot of coding in the MERN stack and Python, and I'm really focusing on Web System Security right now.

I’m trying to decide between ChatGPT Pro, Claude Pro, and Gemini Advanced.

I’d love to hear from you all:

Which one do you find most reliable for debugging complex code?

Which one is better at handling large project codebases (e.g., when I need to refactor or understand a whole system)?

For someone focused on System Security, which assistant gives the most accurate and safe code suggestions?

If you have experience using these for professional-level coding, please let me know your thoughts! Is it worth paying for one, or should I stick to the free versions for now?

Looking forward to your suggestions! 👇
