What's the difference between the Canyon Spectral 5, Spectral 125 and Spectral 27.5?

Per coverage on nsmb.com, theradavist.com, singletracks.com and r/MTB, the Spectral 5 (29er, 150mm rear) is the all-rounder, the Spectral 125 is a shorter-travel, more playful trail bike, and the 27.5 version rides smaller and more flickable but is being phased toward niche use. The 125 is praised for climbing, the 29er for descents.
