I won't sign on to some of the consensus. The result every time I've compared specs is that at full power, efficiency is about equal, and at less than full power the inverter generator wins. Surge capacity depends on the nature of the surge. If it's short, one or two AC cycles, an inverter generator can often handle it seamlessly, while it's already over with before an AVR starts to overcorrect. Longer duration surges are handled better by a conventional generator, and air conditioners present the longer duration surges. My 3.6 kW Onan handles the air conditioner startup pretty gracefully, almost as if nothing at all happened.
