I like the daylight LEDs (5000K) the most, but others can have different opinions, I just like the light that the daylight LED bulbs produce.

For me, it's the same as with other lighting - it depends on where I'm using it, what I'm using it for, and the effect I'm trying to get.

I don't use many LED lights at home but I have 3000K ones in the landscape path lights (12V) and I had daylight LEDs in the garage door opener and refrigerator at my former house but this house has integrated LEDs for those appliances. I have two PAR30 5000K LEDs on a dimmer over the kitchen sink area, and most everything else is legacy lighting technologies (non LED).

Generally I use 4000K to 6500K for supplementing daylight if it's a darker, overcast day, and 3000K and below for sunset and night time. The third layer of lighting is for effects (blue, pink, blacklight, clear mercury, HPS/LPS). I generally don't run the daylight & soft white together. I have only a few oddball lights i.e. SBMV which fall in the special lighting category since they are between 3000K and 4000K.
