I have been using ChatGPT as my primary LLM for the last 2 years. I had heard of Claude during that time, of course, but never really explore it. Finally, I became tired of ChatGPT's tech-bro style of writing and its sycophancy. So I tried Claude and woah, what a difference! It's quite something to interact with an LLM that sounds a feels more human, and yet retains (of perhaps exceeds) the technical capabilities. Also Cowork and Claude Code are at another level. Recommending to everyone I know who use other LLMs to switch to Claude now.
