GitHub Copilot
Pros

- Enterprise tier with private repo fine-tuning makes suggestions specific to your codebase
Cons
- Doesn't understand your codebase architecture - suggestions can violate your project's patterns
- About 30% of completions need correction or are subtly wrong, requiring constant vigilance
- Can't run code, execute tests, or interact with the terminal like agentic coding tools
- Niche languages and newer frameworks get noticeably worse autocomplete accuracy
- Junior developers may over-rely on it and accept bad suggestions without understanding them
