What's your favorite polish?

Cool topic!
For jobs that take a more aggressive polish, I've had great success with the Griots polishes numbered 1-4, with #3 being the best all-around compound. For a less aggressive polish, I've liked the P21S Gloss-enhancing Paintwork Cleanser.
For a final wax on a daily driver, Meguires NXT does a nice job of staying shinny and on the car for a long time.
For final wax/ deepest shine on something that doesn't see much rain, P21S Carnuba works great.
