The Yamaha EF2000isV2 has a higher EPA rating than either the Honda or the Champion.
Basically, engine life rating. Getting two and running them in parallel makes them easier to transport and handle. One will run most everything with headroom. Two will run the AC\heat, as well. I just went through this exercise a while back. My review is in the appropriate section of this forum, if you want more details. The Yamaha also allows you to shut off the fuel so you can run the engine dry. This is important with most fuels containing some ethanol. Not good for your carb if it sits with this fuel in the carb. Also has a fuel gauge. Not critical, but nice to have.
Inverter generators will give you the cleanest power for TVs, AV equipment, computers, etc. And, if you want to be a good neighbor, the added cost will earn you bonus points in the campground.
