Originally wanted the grey a lot more, since it matches the system and I dislike the idea of the two joycon being different. But over time I've grown to appreciate the neon about as much. Still, the OCD in my brain would be pleased to get grey.
...all inferior to how awesome a pure white system would be though. Gonna have a white monitor, keyboard, mouse, tower, 3DS, headphones, and controller. And then a Grey Switch.
