IMO, the last thing in the world you want that front sight to do is catch light, unless you are always shooting in the black timber. Dazzle, and reflection, from a “light catching sight” can fool even young eyes. I prefer a sight with a straight vertical edge facing me. I also like to just barely round the top of that edge thats facing me, so if there is any light catching going on its a very small spot at the top of the blade.
