Hm, it's getting pretty close. Malkin's legacy is already written, I think we can conclude (i.e., if he retired last year or if he retires in three years, nothing changes), whereas Draisaitl is still in flux, so it's hard to be sure.
As far as Drai's career legacy goes, it would probably push his case a lot if he could win not only the Rocket but the Art Ross and/or Hart this season. (At this point, it's possible.) Winning all three of those in one season is pretty unique, and something Malkin never did. We'll see what happens.
I feel like in these comparisons, when one guy is older and basically done (Malkin), it always feels like the "burden of proof" is on the challenger who is still active (Draisaitl). So, it's always better to wait until both careers are done.
Really, the only thing Malkin has over Draisaitl right now is a Conn Smythe trophy, but that's negated by Draisaitl's being one of the most consistent and best playoff performers since 2017. However, Malkin has shown up in a couple of Cup Finals in a big way, whereas Leon was hurt vs. Vancouver and ineffective afterwards last spring. (Before Malkin-boosters judge Leon for his ineffective Cup Finals last spring, go back and check Malkin's first Cup Final in 2008 -- in the first four games, he had 0 goals, 0 assists, and was -3. Why? Because he had the Flu. It happens.)
Check back after this season, but more importantly, check back when Draisaitl is near retirement.
