I am in the process of a long term tea vs coffee war with my partner. I love both but tea is easier on me. Both are rabbitholes and because they are cultural standbys a lot of people grew up with one or the other and like it more because of personal familiarity than actually forming a detached opinion.

A lot of friends over the years who "didn't like coffee" simply formed the opinion because people who didn't really know coffee gave them stuff that was kind of shit. Giving them something on the upper end of the spectrum or is just very different from their expectation can change people into full on coffee drinkers. It's more common in coffee because a lot of people actually don't like dark roasts or are sensitive to stale oxidized tastes.

Tea is generally harder to convert people to with as much enthusiasm because individual blends vary so widely that it can be hit or miss for individual tastes. You need to try people on like several blends over multiple days to find out their profile.
