I like my tea strong and sweet, but with a depth. I use unrefined sugar (raw, organic, fair trade because there is too much slavery still in the world) and once I found the difference in flavor I was hooked and I use raw sugar as a straight substitute in all my baking. This is a bonus because regular refined white sugar crashes my system even in small amounts. I go through 50-100 pounds of sugar a year so I buy it in 50 pound bags to keep it affordable, about $1.30/pound. Same with tea: I can't imagine a day without tea. I buy it wholesale 5 pounds at a time. This makes it about $13/pound, meaning I spend about $20 a month on tea (full disclosure: thesis months see twice as much).
As Thi says, you can go down a serious rabbit hole with tea. I say find what works for you. There's a particular leaf and method that is your personal combination and that's what's kind of great about tea and also about sharing tea. Having a cup of someone's daily brew is like getting a window into their mind-space.
