From Cree I have a strong preference for the warm/neutral tints and like the 5A (Quark neutral) quite a bit, but like the 5B (EZAAw) even better.
Which tint you prefer, regardless of setting will boil down to your own preference but when you see statements of one being better than the other, it's basically a matter of what you like as opposed to what's better.
I'd rather have warm/neutral all the time, indoors or out and the only cooler tints I like will be those with a more bluish cast for their ability to recall moonlight.
