Str adds to smite dmg. Enig has alotta benefits. max life and dmg reduce rocks. u need str for coa so if you dont use enig forget the ber ber coh.
Also any smiter that just uses axes is too damn expensive to be fun. it'll cost you over a million gold to baal run unless u just stand there. I use my zerk grief for dueling cause it has better range but vs some chars like assasins u NEED the faster attack of a pb. Either way u think about it someone WILL find a weakness in your character.
ENIG is my choice cause the str lets you do alot more. and the skills add alot of dmg with only about 30-36 combat smite does like 400 to 450% dmg for smite at combat 41 its like 600% more smite dmg. So forget the fort. I never see a diff other than i cant hold my coa anymore. plus str adds to smite dmg. try taking off your rings for str rings and you'll see what im talking about with 65-70 str from enig its insane. Im not saying dont use other rings but if you check.. str does add to smite.
HOZ does more smite dmg than vortex shield anyday. Eth hoz owns but i like just a regular upped hoz cause u can cham it and have no need for ravens(except for sorb). dungos is cool and the vita is nice but if you pair up arach and cleglaws you'll send melee characters packing since they get so much slower.
Speed and Skills KILL with enigs run/walk and other bonuses you'll be better off. IMO
