How does the 2020/21 Candidates Tournament compare with the 1953 Candidates Tournament?

The 1953 Zurich Candidates Tournament is often recommended by chess coaches as a place to study because of the very high quality of the games played in that tournament.

Blunderprone has an introduction here: https://www.chess.com/blog/Blunderprone/zurich-1953-an-introduction

How does that tournament compare with the Candidates Tournament that concluded earlier this year?

there is a wealth of well annotated games by the actual participants in the Zurich 1953 Candidates Touranament.    Some good amateur players attest to dramatic improvement by reading just that 1 book.

Is there a specific book or collection of annotations that's particularly highly rated?

There is also a book by Najdorf, not as famous as the one by Bronstein.

Is it the Bronstein book that is primarily responsible for the very strong reputation of Zurich 1953?

If a top Grandmaster (e.g. Firouzja) wrote a book of annotated games of the 2020/21 Candidate Tournament that sold well, would the last tournament become as highly respected as the 1953 tournament?

The Zürich 1953 Candidates tournament was 15 players double round  robin i.e. 210 games of 40 moves in 2.5 hours, Yekaterinburg 2020-2021 was only 8 players double round robin i.e. 56 games at the faster time control of 90+30.
You could argue that the 2 players who ended up in last place did not belong at Yekaterinburg and that e.g. Mamedyarov and Radjabov should have been there in their stead, i.e. that the qualification process was not adequate.
Apart from the raw quantity and quality of the games, it are the superb comments by runner-up Bronstein that immortalised the Zürich tournament.

I saw Kasparov did indeed argue the the two weaker players should have not been there and the idea of candidate qualification through Swiss tournaments was not the best way to find the most dangerous world championship challenger.

Zurcih '53 was the peak of tournament/playoff/ chess.  Just my .02 obviously. 

Thank You my friend.  But I wouldn't go that far.  Like i said, its just my opinion.  But I do think that Zurich '53 by Bronstein is a must read book for any serious chess player.  Im doing very well thanks.  Preparing for my first OTB tournament in 2 years.  I hope things are good with you too.

I have played 254 daily games, 335 rapid, 141 blitz, and done 22 hours of rated puzzles training on here, more than 100 lessons, quite a lot in the space of 7 months.

I'd love to be at 1600 already but Rome wasn't built in a day. 

Thanks but let me clarify what i mean by "prepare and study".  My days of serious chess study are long gone.  At 58 my study is a gymnasium for the mind.  I'm just doing what I can to keep as mentally sharp and focused as I can.  The 3 things im not concerned about are my rating, performance, and money.  I'm going to support the tournament, have fun, mental exercise, and see old friends.

A good recipe for living an enjoyable life.
