It may be better to use google, then look at the top results then decide for yourself which one is the best for you. "Which one is the best" is a subjective question as different people have different learning approaches (I find https://learnopengl.com/ a very comprehensive tutorial). If you are looking for a book, then I can recommend you, OpenGL superbible, but that may be better as a reference book than for something to get your feet wet with.
