Extend Dynamics 365 Project Operations if the gaps are narrow and the core model clearly fits your business. That may be reasonable when you only need a specific report, workflow, or add-on.
Choose a different solution if the issue is the operating model. If you need a cleaner connection between project delivery and D365 Finance, fewer workarounds, more standard project business capability, and a path that can grow with the company, PlanAutomate may be the safer choice.
The goal is not to choose the biggest system. It is to choose the path that lets a project-centric company start simply, avoid getting boxed in, and expand without reworking the architecture later.
