Quicker hands doesn't mean better hands. People are mystified by Kane creeping towards the goalie at 3 mph doing a bunch of dekes... He could never do that in a real game because he would get demolished. Kane has great hands, don't get me wrong, but in in-game situations, it's clearly Datsyuk.
They're both amazing. Literally a pick-em, so I chose Kane based on the hometown bias. Anyone who thinks Kane is all shootout doesn't watch many Hawks games, he does amazing things in games. He made Brent Burns look like an absolute fool two months ago, nobody saw it because there was no finish. If I can find a video/gif, I'll edit.
Definitely have to go with Datsyuk. In a shootout it could go either way, but Datsyuk is just a magician with the puck in all situations. It's really not that close for me, unless you're strictly talking about shootouts.
