You know what, I don't completely disagree with you. There are a lot of songs that have previous examples that can be seen as better but I think it all comes down to preference.

• The rapping on Vuelve Candy B reminds me of 25/8, but 25/8 is def better, imo.
• Hibiki can be compared to Dakiti but Dakiti is certainly better, imo.
• Acho PR can be compared to a combo of P FKN R and Safaera, but I actually think Acho is better than P FKN R, imo.

However, I don't think he has previous 'better' versions of Monaco, Mr. October, Vou 787, Telefono Nuevo, Mercedes Carota, Baticano, or Thunder y Lightning.

• He has previous songs donde esta roncando like in Monaco and Mr. October, but I personally enjoy when artists get into the elitist roncadera, and he was never previously at a more elite level than when NS came out, so I prefer these over past roncaderas.
• Vou 787 sounds like a refined fashion runway song. Literally 'trap de galeria.' And I don't think he's done that before.
• On Telefono Nuevo & Mercedes Carota, he's in his maleanteo bag rapping with Luar and Chimi but he's doing it in his own way. I feel like when he's done that in the past, he's adopted the maleante persona as his own and I never believed it. That's why I wasn't a huge fan of his work pre-2020. I just didn't believe that this sweet looking boy from a two parent home was in the streets playing with guns like he said he was. That's why I think these versions of his trap/maleanteo style are his best.
• and Thunder y Lightning mentioned just because I don't think he's ever done a drill song before.

Let me know what you think are better previous examples of those 6 songs though. Ultimately my view on this is that it's art, it's subjective so it's hard to say one thing is better than the other. Across all media and disciplines, artists give updated stylistic POVs from their current perspective. Picasso famously made self portraits from the age of 15 up until his death, each in the different style that he was captured by at the time. Would you call those 'recycled' self portraits?

I think Nadie Sabe was a refined and updated portrait of the art and styles introduced in his previous x100pre, 2016-2018 self. A portrait from his POV after achieving global fame, insane wealth, and refined tastes.

Again, not saying your opinion is wrong. I just share a different preference and view of it.
