I'll sperge out on this because it seems like a good chance to do so
when I was young, I used to prefer tea
then in my teenhood and later years, I began favoring coffee
but the more I grow older the more I actually lean towards tea and I don't know why.
black coffee variants (espressso and ristretto) stopped being exciting for me, it became more of a celebrational/occasional drink than something to enjoy everyday.
truth is on the contrary of your expectations, I don't have a disdain for bitter tastes, I love the feeling.
but there's a very small redeeming factor here, it feels like candy for adults. you get the strong caffeine and the intense boldness of it and it's just not like tea. it slowly stopped being something that I want to sip everyday alone. it also lacks that relaxing feel of course.
that and the fact that tea is just better to make. I can make 10 cups of tea, only one wouldn't turn out to meet my expectations. I make 10 cups of coffee and only one of them i'd say would truly be satisfactory as I imagined.
