My own bias is that Phïsh is playing better. They started out great and never stopped. The ratings are based on numbers. So larger audience leads to larger numbers in the polls for more recent shows. When shows have a lower rating from 1993 than 2013 or 2019, it’s because they way they are ranked is based on number count.

So maybe go by percentage of votes for each year. This will reflect the percentage of votes of people who were fans at the time. So if Phïsh just keeps going and the audience grows and grows, going by percents of votes, instead of number of votes, year by year, can accommodate the growing audience and provide ratings that are reflective of the audience size voting. This will also offer some clarity for past years as well.
