Short answer: Copilot (IDE-integrated) tends to be lower-noise for large batch runs when you want conservative, local edits; assistant models like Claude can make broader cross-file changes but risk more false positives unless you use very large context windows and strict verification.
Practical steps to minimize noise:
- Apply suggestions as PRs, not auto-apply.
- Chunk by module; prompt per-file plus small repo summary.
- Generate codemods/AST transforms instead of blind edits.
- Gate changes with tests, type checks and linters in CI.
