Definetivly the Housing in Wildstar, beside the complexity of the design possibilities, i also liked that you had Plots that gave minigames for visitors.
And yes, i need to agree @Gothix again, the Skillwheel of Original The Secret World i liked so much.
For the fear factor of an permadeath Sandbox game, i point out Salem the Game.
H&H is surely nice too, but with the resets you probably had not such a bound to your character than in Salem.
If i come back to The Secret World, its questsystem with the Investigation quests was for me another point to love that game, beside the amazing lore.
As for the Crafting, i liked it in Salem the Game, since it was somehow grindy, but you did not feel its grind. There was so many steps to do, per example: plant trees, harvest them, make boards on a bench, dry them, plane them, oil them....
You had to raise purity on your fields with a special 3 field planting mechanic.
Purity also was a thing for Fruittrees, Worms for your Compost Bin, Chicken, Planting Pots, surely i forgot something 
If you used different materials you got different stuff from the same receipe.
You had to figure out by yourself, what you have to combine.
I know some other games who have a very nice crafting, that keeps you busy.
It is always interesting, if you don't have to "one click" (like in WoW) to craft, but have several steps, some secrets, a random factor and some effort to do, to get useful Crafts, that you also are able to trade.
For PVP i was also a huge Fan of Warhammer Online, @Shivashanti decribed it well.
