Modern boilers are much more reliable for many different reasons, however primary benefit is always that they're all condensing boilers. All well-managed boilers burn their fuel efficiently, nonetheless they inevitably lose some heat through the hot gases which escape along the flue. A condensing boiler possesses a far larger heat exchanger, so that it recovers more heat, sends cooler gases along the flue and it is more efficient.
Sometimes the flue gases get so cool how the water vapour around the gas condenses out (hence the name), and a lot more energy is reclaimed in the condensing vapour.
