• Firman scores 7.44 overall versus Champion's 6.01, reflecting efficiency advantages

Best use cases

Choose the Firman T04073 if you want the most documented runtime flexibility from a tri-fuel generator in this class. Its 14-hour runtime at 25% load is a real advantage during extended power outages where you're running just a refrigerator, a few lights, and a phone charger. That light-load efficiency means you'll burn through less fuel overnight, which matters when gasoline is hard to come by during a storm. The slightly lower weight of 123.4 lbs also makes it a bit easier to wrestle into a truck bed or reposition around a job site, and the 67 dB noise level, while still loud enough to notice, is marginally more neighbor-friendly than the Champion.

Choose the Champion 201223 if you tend to run your generator at moderate to heavier loads and care more about 50% load performance. The Champion actually edges out the Firman at half load with 14 hours of runtime compared to the Firman's 12 hours. If your typical use case involves powering multiple appliances simultaneously, like a sump pump, a window AC unit, and some lights, you'll likely be operating closer to that 50% range, and the Champion will keep running longer per tank. Champion Power Equipment also has a well-established dealer and support network, which can be a practical consideration if you want easy access to parts and service.

Both generators are conventional models, so neither produces the clean power an inverter generator would. That means they're not ideal for directly powering sensitive electronics like laptops or medical devices without a surge protector or power conditioner. For home backup, tailgating, or job site use where clean sine wave output isn't critical, either one will serve you well.

Verdict & recommendation

If your priority is light-load fuel efficiency and you want a generator that sips fuel during overnight outages, the Firman T04073 is the stronger choice with its proven 14-hour runtime at 25% load and slightly lower weight and noise. If you typically run your generator harder and want the longest runtime at 50% load, the Champion 201223 actually outlasts the Firman by two hours in that scenario.

Both generators deliver the same power output, run on three fuel types, and carry identical warranty coverage. The Firman's higher overall score reflects its advantages in efficiency and portability, but the Champion remains competitive, especially at half load. Your decision should come down to how you actually plan to use the generator and which runtime scenario matters more to your daily needs.
