You can't go wrong with the green tea. You've probably managed to get caught in the middle of a boom in studies that don't really take a comparison of the different teas into consideration. One week they will say black tea is soooo healthy based on this study that proved black tea could save your heart then the next week another article will say the same thing but it will be white tea, or green tea. It will take a while before anyone has definitive proof of one tea being better than all the others since they all have so many good things in them.
It looks like you just want a general "good". For optimum results vary your intake to take the fullest benefit of the varying benefits.
But above all go by what your taste buds tell you. A state of calm can go a very long way for all of your stated symptoms. Enjoying a small cup of tea that you like will do far better than a bucket of one you don't like.
