It's hard to compare these guys as both are very different players, one is an offensive defenseman that will put up lots of points, the other is a defensive defenseman who will shut down the opponent's top lines and play on the PK.
It's like saying who's better between Dan Boyle and Josh Gorges. Both very different players.
A more appropriate poll choice could be, sticking with Oilers prospects, Beaulieu vs. J.Schultz or Beaulieu vs. Marincin.

Exhibit A as to how hockey doesn't matter on ESPN:
Last night an ESPN program was discussing how the Detroit Pistons needed a hero citing the heroes on the Detroit Tigers, Detroit Lions and no mention of the Detroit Red Wings. All this despite the Red Wings probably being the most succesful team in Detroit right now.
I don't really know. I voted Beaulieu, but it's mostly wishful thinking. Most of us probably haven't seen a lot of Klefbom. He seems to be coming along nicely. I wouldn't trade Beaulieu for him, as a Habs fan, but it's easy to acknowledge that Klefbom is the less-risky prospect, and may well become the better one. But for now, I'm satisfied with Beaulieu for the Habs.
