I really like TruGlo TFO sights. They are always bright green in any light. The negative with those sights is that you lose about 1/2" of sight radius on most guns. I had them on the Glock 22 Gen4 that I recently sold to a friend, and he loves them. For him it is a range gun and he uses it for home defense as it is his only handgun. It was a range gun/nightstand gun for me as well. But I never carried it, as I don't open carry.
I won't run them on my sub-compact guns because I feel like I would be losing too much sight radius on a gun with an already short sight radius. I run Mepros on my Glock 27. I like the white ring around the tritium capsules as it allows them to work as both night sights and white dot sights in both high and low light levels and a retain the factory sight radius. If I was going to carry a slightly larger gun I would consider TFOs on that.
I have never seen a set of night sights that were so bright that they would blind me.
I'm also vehemently against lasers as anything other than a training tool for myself. For the same reason I am against battery powered optics on rifles (without a good set of backup sights), batteries can (and do) fail. They are a good option for many, I would just hope that they take the time to train with their sights and not plan to rely 100% on the laser.
On a side note, I have never seen a good grouping come out of a gun with a laser at the range. It seems like many inexperienced shooters use a laser as a crutch, and as such, never learn how to properly shoot a firearm. Typically shotgun patterns are tighter than their groups.
