Give me the ppg elite winger, great hands, extraordinary vision, unreal wrister and creative playmaking skills and you can't even forget how extremely clutch he is. Most important player in the hawks for sure, Toews isn't far behind at all but imo Kane is just the better one of the two.
Kane is more talented but Toews is one of those guys who can be more than the sum of his parts. Like Crosby, Forsberg etc. Toews is not as good as them but he is as hard working and he also seems to improve even when you think he has maxed out.
So, Kane has more natural talent but Toews is better player.
They're completely different. Almost polar opposites.
Kane has much more raw offensive talent and is more fun to watch, while Toews is much grittier, defensive, and overall responsible. Kane very much lives for the glitz of hockey, the sick dekes and the pretty passes; while Toews tends to muck it up a bit more, agitating, drawing penalties, and going to dirty areas to make plays. They serve as a great 1-2 punch and are always put together in conversations for a reason.
With how conflicting their playstyles are, I don't think it's easy to say one is flat-out better than the other. They're better than each other at many different things. It honestly to me boils down to which one is your favorite, and for me that's Toews. I'm not going to vote for him, though.
Edit: I'm surprised at the number of Kane votes. I'm a huge critic of his so I guess you can take what I say with a grain of salt, but to say that Kane is better and it's not even close is the most ridiculous thing I've ever heard. Kane has plenty of weaknesses that Toews excels in, and vice versa. I don't see how they're comparable.
I don't think Kane > Toews offensively is really debatable.
It's hard to compare them though, completely different players that compliment each other well.
I think if you go strictly by offensive skills the answer is Kane (and honestly there are very few players ahead of him in that regard in the entire league). However if you are looking at actual offensive contribution to a team over an entire season it becomes much closer.
