sonnet 4.5 was really bad at anything more than simple queries. even GPT 5 was not great. gemini was consistently good even at 2.5; caught multiple bugs in outputs of either. I haven't tested Opus 4.5 properly at SQL yet, but I've got a feeling Anthropic doesn't prioritize it in training and google does.
I switched to Opus permanently, but I am being cautious. It tends to go berserk and add a bunch of extras. Most of my time is spent narrowing the task to it. Sonnet was much more straightforward forward, but Opus' quality is unmatched when compared. I caught Opus messing up my CSP settings, and I had to restrict the access levels to deeper levels. Using it as an agent with full access without a plan more is suicide with Opus, but Sonnet didn't have this problem.
