Well, wood release, also called Mokuton in japanese, looks the anime way more badass than in real life.
I know it's a very rare kg, possessed by the 1st hokage. Other ppl were able to use it bcoz of his dna.
Wood release is a combination of earth release and water release, and it's very versatile. You could use it for defense walls, domes, attack and much more.
I also know that wood is very strong against bijuu chakra, that is the reason why Hashi could control so many bijuus, and yamato being able to maintain 4 tails naruto.
And I read once that wood is very strong against earth and water, and weak against lightning.
The reason I want to learn mokuton, is just because I think it's pretty badass, a versatile release, So I can use it for many purposes. But I can definitely see myself dropping yamato in the future, maybe because of some other epic release
