I would say Claude is guaranteed (if not already) to take over GPT very soon. The reasoning capabilities, the actual response logic, is way better than other LLMs. As for programming, ofcourse there's no comparison, Claude is the best. But its soon becoming the overall replacement for me for everyday AI tasks in general.
Claude's response and reasoning capabilities are mindblowing. 99% LLMs would just nod along with the user and just agree to what the user is saying one way or the other. Claude on the other hand, rarely does that. It actually analyses and doesn't fret before saying "No, that's not it"
