Mace, Axe, Sword or Staff?

In the quest to create a fun HC viable 2h melee marauder I would like to hear opinions on what 2h weapon is the best.

So the question is Mace, Axe, Sword or Staff?

Why do you think its the best?

Does it have more efficient passive nodes?

Does it accent certain skill more?

Is a rare better than either of the unique versions?

To me fun is never dying. So there's really only ground slam and lightning strike for pseudo melee builds.

Got to endgame on templar using LS. realized holding shift 100% of the time to attack got annoying, rerolled mara with GS and loving it.

so, maces. with groundslam.

Yeah. Go ranged or die, there's no other option.

I don't know what's up with the ground slam really. For me, it sucked. I prefer Glacial Hammer for single target and leap for aoe. I use staff, but thats only because i found one with +170% pdmg ;] I have no weapon-specific nodes in my build, any 2h i have stats for, and works with my skill gems will do.
