From your above preferences, I guess you prefer heavier taste. So you may want to try some darker roast oolong. Oolong is not everybody's favorite, but I guess everybody loves oolong
Some Japanese green tea tastes like vegetable juice to me too, but there are definitely many different flavors in other Japanese teas. And I've noticed some people who think Chinese green has too light flavor, may enjoy the rich, nutty flavor of some Japanese green. I know near nothing about Japanese green and usually just randomly drink it. But I am sure those Japanese green lovers can give you a list of tea away from the vegetable juice taste on the spectrum.
