How do you say "this is cool" in Spanish?

“Esto es genial”, or simply “es genial”, means “this is cool”, but we have many other colloquial ways to say it too. For example, “esto es chévere” or “es chévere”, “esto es chido”, “esto mola”, “esto es bacano”, "esto es rebueno". Most of the time when speaking we don’t mention the demonstrative pronoun “esto”, since it's usually assumed.
