I would suggest:
[item]Iron Gauntlets of the Maiden[/item] with +8 Hit gems for your Threat set.
[item]Bonefist Gauntlets[/item] with +12 Stam gems for your EH set.
Though, to be honest, I do think that [item]Bonefist Gauntlets[/item] with +12 Stam gems and +2% Threat enchant would make a very sexy all around pair of tank gloves. I plan on getting them eventually and using them for my main set once I am done getting other things with my badges. If you just want one solid pair of gloves for most encounters and can make up for the loss of defense in that slot, I would suggest giving it a try too.
