Lacking the spirit of self-sacrifice, I haven't tried as many shu as I could
But if I were to pick 10 of my favorite shus, I could easily imagine giving 4-5 seats to several dayi shu below 10 years of age - some shus above the age would be great too but I think one of the key strength of shu is it doesn't have to be old to be great.
I would give 3-4 seats to changtai products, primarily from 2 blenders.
Then 1-2 seats for products of smaller factories.
I'm pretty sure my top 10 are not the best 10 in the world, because there are several shu on my wishlist and I believe most of them would be fantastic. They remain on the wishlist instead of in the storage, mainly because they are way more expensive than what I'm willing to pay, and I would rather use the money to get more of the shu that I've already tasted and liked.
For any type of tea, it's nearly impossible to let me pick "one favorite", and picking top 3 is not much easier
For people who don't like shu, I'm generally on the same side as you. I like shu, but shu is probably one of the tea genres that I'm less interested in
