I think most of the hatred comes from cold and 'dull' springs. Cold 9 times out of 10 also means dull by spring, especially the further into the season one goes. On occasion, you get the cold and bright combination which, as you say, can be very interesting if convective, or has its own appeal like April 2021 - although I prefer warmth with April strength sunshine, I still enjoyed this month very much despite its chill. Similarly, although I prefer warmer temperatures, the appeal lessens through autumn because it normally also means dull. Ideally I'd like warmth in spring and progressively cooler through the autumn, along with lessening sun strength.
