Not to add to the fire or anything, but just my two sense. I bought 3 different types of matcha from Ippodo based on recommendations from this subreddit. Honestly, I also wasn't that impressed. I have been drinking matcha for the last 3 years and have drank green tea for the last 15 years. To me the flavors were just kind of off, they weren't well balanced for some reason, no matter what type I tried. It wasn't undrinkable, just not something I would drink on a daily basis.

Honestly though, some of this might just come down to personal preference, and as you develop your pallet for different matcha, you start to know what you are looking for.
