If it were me? I'd want flexibility in terms of flow and media customization and would go with an Eheim 2217.
Personal experience? Use a 2217 if you plan to use lily pipes. Use a throttled down 2217 if you plan to use anything that concentrates flow. Definitely use a 2217 if you're running anything in-line (heater, reactor, etc.).
