ive owned 2 XP-E neutrals, 3 XP-G neutrals, and a warm white XP-G quark.
i prefer warm tints, so my favorite from those is the warm tint. but the bin 4seven used for its warm white XP-Gs is really pinkish when compared to the 3000k high CRI XP-Gs.
i prefer the neutral XP-E over their neutral XP-G. i sold my 3 neutral XP-Gs soon after i got them cause it looked greenish to me. but to be fair, most neutral XP-Gs in the 4b range looked greenish to me. i also think its just me, cause im used to warm tints.
the neutral XP-E Q3 3A tints i like very much, and is probably my favorite neutral of all cree LEDs. to me, it looks to have more red hue, than green hue.
EDIT: all the ones i had are from the no longer available limited runs.
i had no idea about 4sevens coming out with a new limited run neutral.... interesting!
