If you find ChatGPT useful, pay just one month of Claude AI and use both. I bet you'll discover that Claude AI can help you a great deal more. If that will be the case, you gained a much better AI assistant. Otherwise it's just 20 bucks... For me the difference is huge.
I have used Claude(Free) for coding and architecture-related questions and found it pretty solid but I found chatGPT a generalist LLM that is good at many things. Is Claude the same? Or you found Claude better for coding related tasks?
