If we're talking wanting to hit through your opponent and end the rally as soon as possible, then yeah, they're probably more aggressive. Rafa and Novak are a lot more measured in their approach. There's a lot more depth to their games. If we're talking ball striking, I'd say Nadal is up there with them, but imparts a lot more spin, instead of just flat power.
I also think there's a recency bias when it comes to Novak. Between 2011-2014, Novak was monstrously aggressive. The only player who made defense an impossibility for Nadal at the time.
I don't think these two compete with that version.
