I’ve been using the Champion 4375 for years and love it. Starts in all weather, less than 70 dBs, strong enough to run my 15,000 BTU AC, and I could keep going. I’ve only ever had a Champion, so its hard to compare it to anythign else, but I’ve never had a reason to switch.
I’ve had both a Honda and a Westinghouse. Both were super quiet, around 50 decibels, and lightweight. But, the Westinghouse is arguably the most efficient of the two. If you ever plan on boondocking I’d go with the Westinghouse.
I’d personally go with an inverter over standard generator. But, as mentioned above, the Champion runs pretty clean and isn’t too loud for a standard generator. Still any of the inverter brands – Honda, Westinghouse, etc., – powered to your needs will be more efficient, quieter, and in many cases lighter than a standard generator.
If budget isnt a concern, I’d go with a dual fuel inverter, like the Champion 4650 or Predator 5000. Quiet, efficient, and can use propane or gasoline. But will set you back about a grand.
I’ll throw in my vote for the Champion as well. I have a dual fuel. Have had no issues with it for years. If I had to buy a new one now, I’d splurge on a dual-fuel inverter. Probably Champion if I could get a good deal. I’m not a brand enthusiast, I just like a good deal 🙂
