Both animes have brother/sister incest motive, with the brother being in love and the sister submitting to him out of devotion. Angel Sanctuary, though, has a lot of additional interesting stuff, Boku wa Imouto is a pure realistic drama.

Both are OVAs centring around the forbidden attraction between a brother and sister in a highly dramatic and angsty fashion. Although Angel Sanctuary has the whole apocalypse thing to divvy the plot's attention between, its focus on the earliest parts of the manga allows the forbidden love component to take nearly as big a role as it does in BokuImo.
