Depends on application. In ST only scenarios, the DoT is less impactful. Still a bit more than the head enchant, but nothing insane.
Now if you add any cleave to the scenario, the DoT damage increases exponentially. Mostly noticeable in M+, but there are a few fights in raid where it does a lot of work.
The active is always at least a 1.6M DMG nuke which is pretty huge for an item.
