I was camped near one of those and was pleasantly surprised at how quiet it was.
However, that's just part of the story. A couple other things have to be considered:
a) does it really live up to its wattage rating and
b) will it still be running after 10 years of hard use?
I have an eu2000i from 2002, and it's leaking a little oil, but it still runs fine along with my other two that are going on 5 years each. I boondock a lot and run air.
The only real maintenance issues (other than oil changes) have been starter ropes that fray and break from the angle they sit at. Usually with a Honda you don't need to worry about parts. Not sure about the Predator.
Good luck!
