Definitely worth it, I'd say. Generally speaking the quality of the leaves used for matcha is different to that of more run-of-the-mill green tea. They're grown under shade and picked young.
We don't drink a lot of matcha but we have our fair share of green tea, lately we've been brewing the leaves in the cup and eating them afterwards, for that extra bit of goodness
We also like soba-cha, hatomugi-cha (good for your skin) and kombu-cha. If they're not available locally you'll probably find them with a quick search on Rakuten. You might be interested to know that rooibos is very popular here.
Last week a friend was upset at the loss of her tea ceremony teacher, who passed away at the ripe old age of 105. Sharp as a tack to the end apparently. Got me thinking, maybe I should start drinking matcha every day too...
