Stockfish 13 is available ( free to download, open-source and likely the best chess engine available on the planet).

Here's the current rating of Stockfish 12 compared to other engines

the new version is improved according to the developers:  "This version of Stockfish is significantly stronger than any of its predecessors. Stockfish 13 outperforms Stockfish 12 by at least 35 Elo.

There's definitely controversy around Fat Fritz 2 which is addressed here.

I am sure chess.com will integrate Stockfish 13 at some point. In the meantime I ran a match on my machine between Stockfish 12 and Stockfish 13: 4 different positions I selected and each engine plays the white and the black side.

First position: Spanish Defense 

Second position: London System

Third position: English Defense

Fourth  position : Sicilian Kan

What was the result of the match played at 4minutes+2seconds ?

Stockfish 13 won 1 game and the 7 other games were drawn.

Stockfish 13 was White in the Sicilian Kan, and the position I chose is sligthly favoring White ( more so than the 3 other positions based on SF)

Here's the winning game
