According to Yamaha website their 2000 watt inverter generator is 51-61 dba and Honda claims 53-59 dba on their 2000 watt unit so they are pretty much the same. I have the Honda and like it but I think I would be just as happy with the Yamaha. I grew up around Honda motorcycles so I am brand partial in that respect. My concern was having a quiet generator in the campground and my second concern was stabilized power to run any electronics you would hook to it like a computer, cell phone or TV, that is the benefit of an inverter generator but you pay for that style. You will find less expensive generators but they won't be inverter style and not as quiet. If you don't need those options or won't be using it on a regular basis, save your money and get a regular generator.
Joe mentioned the Yamaha might be quieter but I think the positioning of the unit and direction the muffler faces might make a little difference.
I also have an 1800 watt Coleman but it is quite loud for a small generator and I only use it when I am not in a campground.
