Maybe I'm living under a rock, but I don't recall many ways of making coffee. I know Turkish way, which leaves the ground coffee in the cup, then Italian espresso, then the way you let hot water pour through a filter with ground coffee and collect it at the bottom. (Perhaps I'm just close minded, but I don't consider instant coffee to be a coffee at all).

Then when you have a coffee, you can add various ingredients to it, like milk, sugar, egg nog, rum... Depending on your preferences.

But with tea you can do the same. Milk, lemon, sugar, rum...

I think it may be because the flavor is stronger in the coffe. With tea, you have more options (green, black, white, fruit, rose, chamomile, even nettle...), but it gets easily overpowered.

Also with tea you need it to stay in the hot water for longer time to release the flavor into it. Coffee beans release everything basically immediately once they hit hot water. Tea takes its time (3-5 minutes).
