My suspicion, CFL tubes generally had plenty of life. On the other hand CFL power supplies had be be miniaturized and high voltage. Many of my old CFL bulbs had melty spots somewhere. So they generated a lot of internal heat with an inefficent supply.
If the LED bulb needs a power supply, it's much lower voltage (and there are an abundance of component choices for those voltages - at least more so than fluorescent bulbs), and there's been lots of work for efficient power supplies in that range. Also there's new no-power supply LED filament bulbs expanding in the market now, and I would think those would tend to last even longer with much fewer components to fail.
