selenium XPATHとclass名で要素を探すときの違い

seleniumを使ってTwitterでツイートするプログラムを作っていました。
ログイン後、ツイートの文をsend_keys()するWebElementをxpathで探したのですが、
NoSuchElementException例外が発生しました。

raise exception_class(message, screen, stacktrace) selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/div[1]/div/div/div[2]/main/div/div/div/div[1]/div/div[3]/div/div[2]/div[1]/div/div/div/div[2]/div[1]/div/div/div/div/div/div[2]/div/div/div/div/label/div[1]/div/div/div/div/div/div[2]/div"}

何度も同じ結果になるので、クラス名で探すとできました。
find_element(By.XPATH,........と
find_element(By.CLASS_NAME,....
に違いはあるのでしょうか？

下記が問題のプログラムです

よろしくお願いいたします。
