Well, Creality hasn't really innovated that much, or as much as others. The Enders and CR-10s (save for v3 cr-10) all use the same/similar hot end and extruder for 10 years. some of the really cool stuff out there are the dual or multi extruders, or the hot-swappable hot-end printers that allow you to print in different colors, or in lite PLA and carbon reinforced PLA in the same model - great for RC planes... Or print water soluble support material so the plastic printed model doesn't need to be cleaned up.
Some of the DIY printers are great - like the Voron2.4
That's my next printer...
Those separate the steppers from the print area and enclose the print area so you can print novel plastics that produce fumes and need venting and stable printing temps that you get with enclosures.
