Yes, the lorry-transported ones are what I had in mind. Part of the
improvement is because they have a massive torquey engine, a massive
flywheel (waaaaay bigger than the engine needs) and a big heavy rotor in
the generator. All this rotating mass adds up to something that won't
change speed much as the load fluctuates.
The little 5bhp Honda gennies are a bit out of this league.

We've
tried small generators as backup to small UPs units, and they
don't get on. Big ones are OK, that's the sort of thing they're
designed for.
What do you mean by 'large' and 'small'? For a VCF-like event, I would
expect one of those large units that's trasported on a lorry, the sort of
thing you use for a large outdoor concert, or an entire (large) building
site, not one of those little things you pick up with one hand and give
you 13A (@240V) if you're lucky.
