What is the most balanced Pokemon move and which Pokemon can learn it?

Question

I want to know the most balanced move to use (accurate,strong,Good added effect, high chance of added effect.) and which Pokemon can learn it and gather STAB from it (get the most out of it)

Comments

You need to be more specific about "balanced", apart from just saying accurate and strong. Pokemon gain STAB (same type attack bonus), so that has to be factored in as well. EDIT: it's not just STAB. Are you talking about coverage? It differs from type to type, Pokemon to Pokemon, due to movesets/ stats. There are still too many variables to answer this accurately.

honestly there are too many moves

Answer 1

I think it's Earthquake. 100 Base Power, with no drawbacks, and has full accuracy. It's a Ground-type move so it gets a lot of coverage.
