I've had to replace the front sights with a slightly higher sight on my non-Trapper M94's ( with the front sight mounted directly in a barrel dovetail ILO on a ramp) - but I took it as an oportunity to also change the front sight to a bead type more to my liking ( Ivory/Gold//FiberOptic/etc).
I usually mount a Williams 5D, since it's a "set-n-forget" sight, where one load is generally used at a single sight setting like for general hunting.
The FP and the Lyman both are easily/micrometer adjustable for W/E, for those who want/need to be constantly readjusting their sights - a better bet for certain types of shooting, like silly-wets.
The Williams sights have always been made from a very strong aircraft aluminum, with vintage Lymans of steel - but no longer. the latest Lymans are now also aluminum.
They will all accept various sized apertures, and can all be used as a "ghost ring" peep by shooting with the aperture removed - so the answer is much like asking your preference in dance partners (It's YOUR choice)
