I liked Superjoint Ritual, it's not awesome or anything but i consider them a decent Anselmo project.
Down are great, i still not heard the latest album but it's on the waiting list ready to go.
Hellyeah and Damageplan are "meh", i don't dislike them but i don't care much for them, i agree that the vocalist from Hellyeah, ruins most of their songs...
