Decision framework
| If you need… | Lean toward |
|---|---|
| Lowest friction daily coding | The tool that matches your IDE and VCS stack |
| Long-horizon refactors | Stronger multi-file / agent features |
| Cost control | Compare Paid vs Open Source plus inference |
| Compliance | Confirm DPAs before enabling cloud agents |
Many teams pilot both for two weeks on the same ticket sample, then standardize on one primary tool and keep the other for specialized tasks (reviews, migrations, or docs).
