Let's say I am talking to my friend about some rock band or restaurant and describing how much better it is, compared to some other band. I say
- You think this album is good, wait until you hear the album Y. Compared to Y this album is just a preview.
- If you enjoyed the X show or Y restaurant, then you will definitely like Z. Compared to Z, X or Y is just a preview.
