If I'm using cursor then sonnet is better, but in claude code Opus 4 is at least 3x better than Sonnet. As with most things these days, I think a lot of it comes down to prompting.
This is interesting. I do use Cursor with almost exclusively Sonnet and thinking mode turned on. I wonder if what Cursor does under the hood (like their indexing) somehow empowers Sonnet more. I do not have much experience with using Claude Code.
