Long-term I think Ennis is your guy.
But I would probably grab Lucic because if he has a big year with a nice PIM/point combo, he'll be better trade bait, and a potential keeper in a keep 9. Whereas if Ennis just ends up with say 40 points, u may have to do a bit of convincing to a GM that he has long-term upside.
Also keep and eye on Burrows for the same reason. He's off to a slow start, but if that changes you'll want him on your team.
So to sum my ranks are:
1. Lucic
2. Ennis
3. Burrows - but if he gets hot on the Sedin line he jumps to #2
