Exactly.
Islam will probably have a better resume, but he already got KO'd, so Khabib beats him in terms of a perfect record.
At striking, Islam is better and more natural.
As an overall fighter, Khabib is the better fighter and better man. Makhachev himself says, "In the cage, no one beats Khabib," including himself.
Khabib is less fragile, rougher and tougher in his ability to take punishment — and far more fierce and relentless in his constant attacks — as well as his absolute domination while attacking.
Since Makhachev himself admits Khabib is the better of the two, that's pretty much the end of any further debate concerning overall prowess.
So yeah, Islam might be "more rounded" as an MMA fighter, but he will still get his ass kicked by Khabib.
