I am pretty much over Glock pistols these days, having reduced my inventory to only two . . . . a G43 and a Gen 3 Vickers Edition G19.
I shot G17's, G34's, and G19's pretty extensively in competition for about three years, and carried one version or another of the Glock platform regularly.
Tried lots of trigger combinations, including "do-it-yourself" and aftermarket.
My personal all-time favorites were from glocktriggers.com
The Gen 3 Vickers G19 I still own has one of their "Vogel" model triggers and the G43 has one of their "G43" models (imagine that!).
But the single best trigger I have ever felt in a Glock pistol were the "Edge models from glocktriggers.com that I had in two Gen 3 G34 pistols. The "Vogel" is almost exactly like the "Edge"model, but the pre-travel hasn't been removed from the "Vogel" model.
I shot Bob Vogel's G34 with a "Vogel" trigger in it in Texas at a training seminar and his trigger felt exactly like the one I have in my Vickers G19.
I never had even a single reliability issue with ANY of the "Edge", "Vogel", or "G43" triggers, and that included LOTS of shooting, with handloaded mmo and numerous brands of factory ammo.
