It's not only brand-dependent. Over the last few years I noticed that my LED lamps died quite often during the period when our mains voltage was on the low side, usually in the 200-210V range (nominal value is 230V, allowed deviation is +/- 10%). The damage was always the same: one of the leds burns out with a clearly visible black dot on the die. It was possible to repair the lamps by shorting the burned LED with a jumper wire.
Later, when they changed something and voltage started to be usually in the 230..250V range with the most frequently seen value being about 240V, the lamps began to die very rarely. Those that die, do it slowly: they begin to flicker randomly etc., eventually failing. I didn't find obviously burned LEDs in those failed lamps.

There is another valid reason some prefer incandescent. In parts of the midwest USA there are very frequent thunderstorms, lightning induced power surges are very common and destructive to electronics, Incandescent is much more robust and resistant to surges. I also have to admit that the light quality of incandescent is at least slightly better than even the best LED bulbs. You just can't beat the smooth continuous spectrum, perfect 100 CRI and complete lack of flicker. Good LED bulbs are good enough for most of my purposes but if energy were free I would still choose incandescent for many of them.

Huh? Incandescent lamps flicker. Its 100Hz/120Hz and doesn't go anywhere near zero, but its there. A decent LED has a really steady output.

LoL, what a bunch of twaddle. I have had many bulbs pop due to a storm or power issues, the LED stuff seems to be holding up quite well. The LED panel I have in the shed is awesome, almost no shadows from it. I have LED sidelights and brake lights on my 110 Defender and on the many motorcycles I have and they deal with the bumps really well I seem to hardly ever have an issue with them compared to the 6V bulb on the Matchless that only needs to be looked at wrong and it goes *fizz* *pop*.
Will admit I was surprised by the CRI of 100 but that is making me wonder about the index in the first place. Floucesents are just horrible but I remember it was common practice to take photos we had processed in the darkroom outside so we could get a look for the colours in natural light as almost nothing compared to daylight. But even that has its moments depending on the time of day, weather, and angle of the gas ball in the sky. I am quite sensitive about the colour of light and I notice the changes more than most.
I think the general idea as suggested way back in this thread is if you could convert a significant proportion of people to convert then as a population of millions that makes a significant difference.
The only issue I have with LED is the noise.

They make surge suppressors for that. They're not even that expensive.
