Well, you weren't very clear in your post, it does not look like a review request.
Trijicon is always good, as is meprolight. The truglow with both the fiber optic and tritium, and the fiber optic is enclosed in steel isn't bad either.
I didn't much care for the xs big dot. While the front was nice, the shallow "v" for the rear, not so much. For across the room, "metal on meat" shooting, it's awesome, but for any distant, accurate shooting, not so much.
I've personally gone more towards a front night sight, and standard rear. At the distances and light levels you would actually pull a trigger for, it's enough.
Just my opinion.
