I'm going to have to go against the grain and say "Armor".
If you're talking about ebon, then you are getting to the point where you will probably start raiding, or at least doing some of the bigger quests. There are plenty of heritage rewards, quest rewards, and fabled weapons that are much better than any imbued weapon you can get.
There seem to be very few fabled or rare medium armor pieces in the game that are better than imbued ebon.
