    If the condensing boiler can run constantly at varying firing rates, then it'll hit that steady-state nirvana almost 100% of the time. The other boiler will cycle on-off which means increased losses until the HX hits its steady state. Plus, the condensing boiler can operate constantly even when the water temps to supply the load are very, very low.
