Composer 2.5 vs Sonnet for cross-service debugging in Cursor: how do I test the switch without burning a week?

Replay solved incidents. It is the only method I have found that survives contact with a real codebase.

Pick three bugs you personally fixed and know the root cause of. Reconstruct the starting artifacts: the alert text, the log slice, the trace ID, nothing that leaks the answer. Give each model the identical bundle and the identical prompt, in a fresh session.

Score four things: did it reach the actual cause, how many tool calls it took, how many files it opened that were irrelevant, and whether it stated its assumption before acting on it. Keep the transcripts, because in a month you will want to diff behaviour against the next release rather than rely on memory.

Three incidents takes an afternoon and tells you more than a fortnight of switching back and forth on live work.

Cursor's $20 plan vs ChatGPT Plus at $20: how do you compare them after the July changes?

Log why you stopped, not just that you stopped. Run the same ten tasks in both for a week and put every interruption in one of three buckets: quota, quality, or speed.

Most people are certain they are quota-limited. When I did this, over half my stoppages were waiting on a slow reasoning mode and giving up, which no amount of extra allowance fixes. That reframed the decision from "which plan gives more" to "which one is fast enough that I finish".
