Yeah, I think I'm officially a tea snob. A spoiled tea snob, I think.
My absolute favorite teas are from Le Palis des Thé - specifically their Fleur De Geisha and Thé des Alizes. I blame my mom and uncle for getting me gifts of these teas on numerous occasions as I'm not sure how I'm going to restock after I run out. I don't think I can bring myself to do an international order for tea, no matter how good it is.
Tazo, Stash, Good Earth, and Twinings bagged teas are okay - and usually what I have on a daily basis. Although, Stash loose leaf is much much better than their bagged. I'm lucky enough to live close to their outlet store where their loose selection is available. The best bagged tea I've had is Zhena's Gypsy Tea. The fireside chai is awesome (especially with some milk and honey). Plus, it's caffeine free so I can enjoy some chai at bedtime.

Teavana is also quite nice, although ridiculously expensive.
I had almost given up on Adagio as the teas I had previously ordered were lacking in flavor and a bit stale. However, the last order I did restored my confidence in them. The decaf spiced green (thanks Chris!) and the dewy cherry are really good.
