larger wastegates can flow more (bypass more exhaust from the turbine wheel) so they allow you to run lower spring rates without creep. But there are a lot of factors that go into wastegate flow requirements. The size of the gate really depends on the turbo, the boost level, the budget, fitment constraints, noise constraints, etc.
