Which platform should you choose?
Start with a representative task and the people who will do it. Evaluate repository access, generated-code correctness, test quality, command permissions, and review effort. Test the same inputs across your shortlist and record output quality, manual work, and current plan terms. Validate claims with the vendor and test the important workflow with your team. Differences shown here are evaluation prompts, not hands-on performance findings.
