I think the tea bags we have here are OK. I think the bags themselves are constructed better because if I make a whole pitcher of tea (for iced tea), I have to use a coffee filter with the Yorkshire to keep from getting loose tea in the final brew.
Most people drink Lipton, Tetley or Luzianne if they're making huge pitchers of iced tea - we probably drink a couple gallons of that a week and always have some in the fridge.
Then, there are other fancier brands in smaller packs that are nice.
But, for hot tea, I liked the Yorkshire better than most of our brands. I did fine Yorkshire Gold over here in a specialty grocery store, but I didn't like it as much as the plain Yorkshire that's more red.
We also have a few tea shops that have sprung up that sell specialty loose leaf teas, but I'm not a tea snob, and I'm thinking they're probably pretty expensive, so I'm staying out of those places.
