We are already 1/3 into the year, and I think that at this point, we could make some fairly accurate comparison between strength of the tennis field this year and 2011. Now, please note that we will be looking at it from the perspective of each year's most dominant player, namely 2011 for Djokovic and 2024 for Sinner, meaning that for 2011, we will be excluding Djokovic and for 2024, Sinner will not be counted.
Top competitors in 2011:
Nadal
Federer
Tsonga
Murray
Berdych
Top competitors in 2024:
Djokovic
Alcaraz
Medvedev
Tsitsipas
Ruud
And I will be giving my opinion (please note, this is just my opinion. I don't intend to troll):
On hard courts, I think they are about even. Djokovic, Alcaraz and Medvedev are superb on hard courts. Carlos has just won Indian Wells in a dominating fashion, Medvedev reached the AO final, and as for Djokovic, well, he is a 14 time HC Slam champion. Nuff said.
In 2011, you had Federer, Nadal and Murray. Djokovic has a better record on HC than Federer. Nadal's level on HC was very high that year, although rather short-lived (at only the Sunshine Doubles did he show his peak HC level, and other than that, he was very underwhelming for the rest of the season), and Murray reached the AO final and won Cincinnati. But other than that, nothing else notable.
On clay, having Nadal really helps the 2011 field to edge out the 2024 field. But without Nadal, then I would have to go with 2024. Tsitsipas's and Ruud's level at MC were comparable to Federer's level in RG 2011 semi-final. Nonetheless, ignoring Nadal here would be massive cherrypicking, hence 2011 takes the cake.
On grass, we don't really know yet... I will come back to this thread in July.
With that being said, I think that 2011 was an incredibly overrated year in terms of level of competition. Particularly Djokofans love to hype up it like it is the strongest year ever, but it really is not. In fact, far from it. 2011 was still a part of the weak era, to be honest.
What do you guys think? 2011 or 2024?
