Are you really asking us to compare a 23 year old who has been playing pro hockey for 6 years to a 18 year old rookie?
There’s an underlying premise in the OP that, yes, given his age and recent performances, Stutzle probably has a higher ceiling. So the premise is to create a more interesting poll than to get 200 people rushing in here to hype Stutzle because he was just picked third overall and had a great WJC and is only 18/19.
There’s an extreme lack of reading comprehension issues in this thread. The amount of “lolol Stutzle not even close!” responses fall into this category. If the question doesn’t at least give you pause to think, you are simply being either willfully or unintentionally ignorant. KK’s 22 minute, 3 point, game winning breakaway goal debut makes it pretty clear he is, despite Stutzle’s lofty expectations, much more likely to have a Calder type rookie season.
So if Stutzle is the long-term bet and KK is the short-term one, does the 3 year window proposed in the OP give Stutzle time to pass KK or is KK simply going to be an elite star forward right from the jump given his experience and thus making it more difficult for Stutzle to pass him in 18 months (the mid point of the time frame which would throw the balance in the other direction).
It’s a question that requires actual thought and knowledge of both players, not hyperbole. It’s a good premise wasted by a bunch of responses that don’t seem to care to take the time to understand it.
Even beyond the OP’s parameters, why can’t they be compared, fwiw? They are top 10 prospect league wide, both are dynamic forwards and both are rookies this year? The NHL is likely going to be comparing them for the Calder Trophy at years end...
