You still want sharpened.
Otherwise you have 4k from spinners and losing just over 5k from dropping sharpened. Why use a 5 piece for the less pen you get from a sharpened weapons.
In pve everything has 18k resist. You want to strip as much as that as possible.
In PvP, over half the people are running heavy armor. 18-25k resist on most builds. Again, stacking pen negates a lot of that armor.
So yes, you still want sharpened.
