In honesty I think the league was poorer in 2019-20 when Liverpool were the only team in the title race for pretty much the whole season an were well clear of everyone else by the end of February, I think they were 25 points clear when Covid halted the season after 25 of 26 games.
Liverpool were 25 points clear of City when covid halted the season, but City actually had more points than Arsenal did at the equivalent stage of this season and finished with more than Arsenal can get this season.
The newly promoted sides not showing up (again) this year has skewed things a bit, so it might look like the chasers are a bit stronger in terms of points won, but they're simply just ahead of a really poor batch of relegated sides.
In 2019/20, only one of the top 17 won every point available against the bottom three (Burnley, weirdly enough). Two have already confirmed that status this season (Liverpool and Newcastle), and another four are on track to do so (Arsenal, City, Forest and Brentford).
Including Burnley, seven teams won over three quarters of the points available against the relegated sides in 19/20. That number is guaranteed to be 10 this season.
12 teams won over two thirds of the points available against the relegated sides in 2019/20, that number currently sits at 13 this season and could be as high as 15.
Every single team in the top 17 has won over half of the points available against the bottom three this season, and only 13 did so in 2019/20. If you drop that to half or more, we're guaranteed to have at least 16 teams, but it'll stay at 17 if Everton can beat one of Ipswich or Southampton. It was 15 teams in 2019/20, with both Leicester and Newcastle only winning 44% of the available points.
Perhaps most notably, only one team in the top 17 has dropped points against every relegated side this season (Brighton, although they've remained unbeaten), and it'll remain that way if West Ham and Everton both beat Ipswich. Three sides did so in 2019/20 (Arsenal, Spurs and Leicester).
226 points have been won by the top 17 against the relegated sides so far this season, 12 more than were won in 2019/20, and there are still another 24 up for grabs.
They've quite simply failed to make a dent in the league and have essentially guaranteed every other team at least 10 extra points.
