>Confagrigus for pure bulk>Mismagius for Sp.Def and Sp.Att>Dusknoir for Bulk and Attack Mismagius is the fastest of the three, while Confa is the slowest. But it makes up for it with its bulk
Personally, Dusknoir is your best bet if you're looking for raw power and spectacular bulk. It hits like a truck and can talk like a truck, which is useful against Ghosts and Dark's since most of their moves are either Physical or Special. But don't be fooled, even though it has high Def and Sp.Def, it's HP is low. So don't get overzealous.
Confa is good, especially since it has higher HP and Defense, but it is much slower that Dusknoir. But its ability can screw with opponents, which is neat
Mismaguis is your best Sp.Att glass cannon. It's not as heavy hitting as Gengar, but it hits hard. And it's faster than the previously mentioned Ghosts.
tl;dr Mismagius for waifumon, Dusknoir for bro, Confa for wall
If you're looking for dual types then it depends
