Yeah, they’re Nichia 219Bs.
Strictly speaking, it’s a matter of opinion. The XP-G2 has slightly better efficiency, at least compared to the high-CRI version of the 219B, and will produce a slightly more focused hotspot in most optics.
On the other hand, the color vividness and accuracy with a 90 CRI 219B compared to an unspecified CRI (usually about 70) XP-G2 is large improvement. That colors are more saturated and similar to how they appear under sunlight with the 219B is not a matter of opinion, but a verifiable fact that can be tested with a photospectrometer. This makes it easier to detect and identify objects that blend into their surroundings and to see details. Many people find the light it produces considerably more pleasant to use as well.
So my opinion on the tradeoff is quite strong. I always replace low-CRI LEDs in lights that come with them.
