I'll take them as:
Malkin: got the best blend of size and finesse skills on top of hockey smarts, making him very era proof. Only knock is inconsistency (but part of that is him playing through injuries). He's the only player on this list who I think will end up underrated by the hockey world.
MacKinnon: got the wheels and the hands to mam plays at speed like "mach speed" as Pat Lafontaine called it. Perfect skillset for his era. Insane work ethic though and willingness to improve which would help in other eras as well. Also got decent size. The perfect player right? Unfortunately, unlike the other mach speed player of his era, McDavid, his head generally doesn't keep with his hands and feet, he plays too individualistically and forces stuff a lot, not utilizing the all world talent around him when he should. If he was just smarter, I'd think he'd be even better than McDavid given his physical gifts and work ethic.
Draisaitl: His stock rose for me this year as he again showed he can be the Oilers best player and for a long stretch of time this time (was probably the best player in the league this year). Good strength and size, very smart player, he has drastically improved his skating. The only player in group who can reliably score at distance. Inconsistency and laziness was an issue in the past but not so much this year, he is a big whiner and diver but while that's hateful, it works in this era.
Kucherov: He's an absolute genius no doubt, probably smartest, definitely smarter than MacKinnon, but just lacks the physical talents of the guys above him, and I feel of all these guys his stats are the most inflated, and he is the most era dependent.
Kane: Kroger brand Kucherov
