I always just drink tap water and find it better tasting than bottled. But I guess that varies by where you live. Do most people in the US drink 100% bottled?
I'm in New York and I don't like tap water at all (a lot of people do though). I used to drink bottled water only, but it was not convenient as I could easily forget to order a new pack, so I switched to Brita filter + tap water. So far so good. I don't believe a $40 filter does a tremendous amount of filtering, but it seems to be OK ¯\_(ツ)_/¯
