In the 90s you might be weaker on clay/grass / slow courts / fast courts. You might play better against grinders or serve and volleyers. Nobody has those concerns anymore. While being dominant is still a huge feat mentally, in terms of tennis skill it’s not nearly as impressive.
I definitely agree with all of this. I was simply pointing out by statistics and actual results which determine what is considered the "greatest season(s)" (which it is clear was the discussion point) many of the ones listed never had a season to compare to Nadal or Djokovic's best, let alone Federer's. Yes it is an awful lot easier to dominate today and post a season like that today though. Federer, Nadal, and Djokovic have all capatilized.
