It's the most novel and riskiest. I wouldn't say it's hardest. That's launch, reëntry and reüse. They've substantially de-risked those components with IFT-11.
I'd put IFT-12 validating Block 3 as the actual hardest launch next year. If that goes smoothly, I'm betting they make orbit and propellant transfer before the end of the year. And if that happens, I'm betting they get at least one rocket off to Mars before year end.
