I like the flavors that Kekou had to offer - in addition to the standard green tea, it also offers other Asian flavors like Hong Kong milk tea, which has a great mix of subtle sweet and black tea taste. Portion is a little on the small side given the price, but if what they are claiming is true (no stabilizers, ie. fresh, xanthum gum, carageenan and gelatin), then I think it's worth it.
I'd recommend the less visited flavors, like the HK milk tea or oolong - off the beaten path and still as delicious.
