Conclusion:
While the Optima Steamer clearly wins in terms of raw power and specifications, the Chief Steamer 125 offers a balanced, versatile, and cost-effective solution for car detailers who need comprehensive detailing capabilities rather than just consecutive exterior washing. The choice ultimately depends on the specific needs of the user.
