I have basic truglo metal sights, just tritium, no fiber optic. I do like trijicons better. I think as long as they are metal and have a vertical front edge on the rear sight (so you can run the gun one-handed) you should be ok. The truglos are a very cost effective option and I like them. I had XS big dots for years before that and I don't like them any more. I have found in a stressful situation you don't use your sights hardly at all, and if you do you want them for a precision shot, so the big dot is kind of pointless. I shoot better with the new sights than with the XS sights.
Style is a personal thing. I run XS dxt2 big dots with the large glowy green front dot, there is nothing faster on a defensive/carry gun. My second favorite is the Trijicon HD's with the orange front dot.
