The tri-fuel showdown: both hook to your gas line and power a whole panel indefinitely. The Westinghouse is an inverter — 10 dBA quieter (a massive real-world difference) with grid-clean power — for about $450 more. The DuroMax counters with more raw wattage per dollar and a longer track record. Quiet neighborhoods and sensitive electronics justify the Westinghouse; pure capability per dollar says DuroMax.

Pick the Westinghouse if…

✓Overnight running near bedrooms or neighbors (64 vs 74 dBA)
✓Clean low-THD power for electronics-heavy homes
✓The refinement package: quieter, lighter, more efficient

Pick the DuroMax if…

✓Maximum watts per dollar (10,500 vs 9,000 running on gas)
✓Proven platform with years of owner history
✓Budget capped under $1,600
