If you own one of them

Whether to move is a different question from which is better. Each Mac has a page on it: what its successor changes (the newest Mac in its line where Apple sells one, otherwise the Mac this site treats as its replacement, which can be in another line), what it fetches and whether it still gets updates.

The pairs a buyer of either Mac would also weigh. Any two Macs in the catalogue can be compared from the chooser.
