Claude the model is good but not amazing, O3/GPT5/Gemini 2.5 are better in most ways IMO. The Claude model does seem to have been trained on tool use and agentic behavior more than other models though, so even though the raw benchmarks are worse, it's more performant when used for agentic tasks, at least in terms of not getting confused and making a mess.
The big thing with Claude Code seems to be agentic process they've baked into it.
