24 is the famous move of that famous game.
24.Rxd4 is also the best move, according to stockfish, but not according to chess.com's shallow analysis... probably best to use chess.com analysis on beginner-level games as that's what they designed it for 
"There are no exclamation marks, as they serve no useful purpose. The best move should be mentioned in the analysis in any case; an exclamation mark can only serve to indicate the personal excitement of the commentator" - GM Dr. Hübner
Actually, chess.com should raise the bar for great moves and brilliant moves. Obvious moves, like taking an undefended piece, are sometimes called great moves, and the first move of a 3-move combination is sometimes called a brilliant move. I assume these over-generous assessments are intended to keep players happy, and keep them coming back to the site, but they show disrespect for the game of chess, in which flashes of true brilliance are both exciting and rare.

Great moves are just the best move in a position where there is only one good move; in other words, when any other move would be a inaccuracy, mistake, etc., so there is no bar to raise when there is one objective definition of a great move.

That's not what I would call "great."
In the game review, chess.com should make a triple exclamation move for exceptionally brilliant ones.
