MK2 models for me. They’ve got a more grown up, classy, professional look. They MK1’s have a bit of a toy like quality to my eye. No problem with the grey especially when 90% of all other gear is black. Better screens with improved graphics too. I love the form of the Analogs too. Sculptural with a definite design quality rather than squat rectangular boxes
I don’t expect many others will agree with me but that’s irrelevant, beauty is in the eye of the beholder.
