-Your task is to analyze multiple plans and select the best one based on:
-1. **Feasibility** - How realistic and achievable is the plan?
-2. **Quality** - How well does it address the requirements?
-3. **Efficiency** - How minimal and focused are the changes?
-4. **Maintainability** - How well will this approach work long-term?
