For pvm, I think the beast and ebotd would be the best of what you listed do to the large amount of hits (from 2 weps and fanat ar boost) and high avg damage along with the crushing blow and open wounds from beast.
However, I think a ebotd great poleaxe or ghost spear would be better than any of those listed, due to the HUGE damage and 5 range compared to 3 from zerkers.
Botd+beast easily, both for pvm and pvp. Phoenix is worthless.
Beast as secondary gives the same avg dmg as 2x botd or 2x grief, but you also get ar, crushing blow (useful in pvm), open wounds (useful in pvp) and ias for berserk.
Grief+beast is of course better if you're on ladder.
