I've found one thing certain with tea, my preferences change over time! So I can say something now, but months from now...or years I may have a different view.
With that said, in addition to Pu'er my 'other' favourite is Sencha. I would put them both at a tie for first place. In fact, Shou, Sheng and Sencha are in a 3-way tie for first. I guess the tea has to start with an 'S' to get considered

Favourites early on in my tea journey included Darjeeling and High Mountain Oolong, with Matcha making an appearance for 6 months or so. I've also had a lot of Wuyi and Dancong over the years but never a favourite of mine.
Lately I've been gravitating away from teas with mineral taste profiles. Never know what the future will hold though!
