Not sure what you mean. The current lineup is basically the Retina MacBook, non-Touch Bar MacBook Pro, and the two MacBook Pros with Touch Bar. The first is for consumers and those who need an ultra portable, the second for people who want more power but don't need the latest, and the final two are for power users.
You can basically ignore the MacBook Air and 2015 MacBook Pros because you can't even find information on the 2015 MBPs unless you click on the bottom of the MBP part of Apple's website for more options.
