BUIS on shotguns

[Plink]

Thinking about taking off my red dot from my 870 and tossing on some irons.
I've seen some different ghost sights and BUIS around, but am not really sure what to put on.

What are your folks experiences with irons, and what are your "go to" brands etc.

I've got Trijicons on my 870, I think they're either the same sights as the Wilson/Scattergun ones or else very close. They're great for shooting slugs.
