tried out a space black 14" MBP M3 at Best Buy, and liked the color more in that moderate lighting than under bright lighting of Apple Store where I was underwhelmed. Under normal conditions, I think it does look a little nicer than Midnight and initially thought the exact opposite.
The keyboard does feel different from memory than M2 Pros when I played with those in the store, but could be down to unit variation like anything. I still prefer the feel of my 15" M2 MBA.
Also, the trackpad felt good and not grainy on the unit I was playing with. But to be honest, it felt identical to how my good trackpad 15" Air felt, not any different so...
