Between the Trijicon (on the Glock) and the Novaks (on the BHP), it's a hard choice. The Novaks have a "finer" sight picture I attribute mainly to a narrower front sight. The Trijicons are simpler due to fewer "surfaces".
The main objection I have to the Novaks is that the sight picture is complex. While the curved sides and recessed rear provides high contrast, light reflects off the outside rear rim and bottom rear "shelf" of the sight. I highly dislike this effect and find it distracting when acquiring a sight picture fast or shooting at-speed.
That said, I prefer the Novaks to the Trijicons because the Trijicons on the Glock are generally more visually bulky, covering up more of the target. Namely, the front sight is wider on the target compared to the Novaks.
I also dislike dots unless they dots are exactly aligned and the front dot is fully visible when the tops of the sights are lined up perfectly. The brain wants to "see" the front dot fully, and this can lead to aiming too high if it is not so.
