So, I guess I was not the only one who listened to a Haydn "complete symphonies" box during COVID. My box is probably more modest than yours, James, but still complete
("Haydn Symphonies Complete", Adam Fischer conducting the Austro-Hungarian Haydn Orchestra):

I had heard one Haydn symphony as a youngster, concluded that "Beethoven totally kicks his butt," and never circled back to give another listen until getting this box set - perhaps I was a bit shallow and hasty in my judgment!
While I listened to all of them, it was not very focused listening (I was working at home at the time, so it was background music). It is a massive amount of music (this set recorded from 1987 to 2001). At the time, I was looking at a website where a classical music writer was given an assignment to listen to all the symphonies and "put them in order of brilliance," but was (of course) very superficial and not meaningful.
It was on my mind the last few days to ask if you had listened to many Haydn symphonies (and now I know!), and if so, how you would think about exploring this music. I am aware that the relatively late "London" and "Paris" symphonies are notable, as are the earlier "Sturm und Drang" symphonies.
Any thoughts you can share off the top of your head? Any there any that are your particular favorites?
(By the way, apologies in advance - I really appreciate and enjoy all the insights you share here, but please don't feel obligated to answer this kind of random question involving over 100 symphonies!)
