I have all three!
On differnt guns. I have adjustable meps on my new G34, I honestly can hardly tell them apart from my 6 year old tri's except the meps are a tad brighter. Also the finish is coming off which is kind of troubling because the gun is a range gun and is carried cradled in a soft blanket. I like that they are easily adjustble, on that gun anyway.
I just got truglo TFO's on my new 23 and they are GREAT!!! I have a feeling they could be a little more fragile though, there is more to them. It's my nightstand gun, I try to be careful when cleaning to get as little solvent on them as possible. They are large bright and clear!
Nightsights are great, I put my glasses on my gun so if I need them I just look for the glowing dots.
