Highlord's has everything I need: +skills, light res (for immunity when wearing TGod's), ias, and DS (I use Jab to take out phys immunes, plus the extra chance to do double damage increases my chances of leeching back all the mana I'm using when not Jabbing). I, like Evrae, also would have trouble getting ias from elsewhere besides gloves; armor=Duress, helm=griffon(facet), shield=Sanctuary.
Mara's gives more +skills, more stats (only amounts to 45 life if stat points are saved for vit), and better resists. It's also quite a bit more expensive. So if you need the resists, the extra +1skills, don't mind sticking a Fervor jewel in your gear, and can afford it, go with Mara's. Otherwise I think Highlord's wins.
