When it comes to describing something as the "next best," several synonyms come to mind. For instance, you might refer to something as "second to none" or "second best." Similarly, you might describe something as "almost as good," "close to the top," or "not far behind." Other potential synonyms for the "next best" might include "runner up," "silver medalist," or "highly commendable." Ultimately, the choice of synonym is up to you and may depend on the specific context in which you're using the phrase. However, whatever synonym you choose, it should convey the idea that something is very good, though not quite the absolute best.
