It's great that they are mechanical and haven't forsaken contours, but since we're among old snobs... sigh I'll never get that "lets shove everything together into a sea of keys" layout (so prevalent in the mechakeyboard scene nowadays as well).
All those off-center keys have been grouped, offset and/or specially shaped since ages for a reason - to immediately and unambiguously settle your fingers there with minimal error when you have to move you hand away from the homerow anyway.
Many things. The feel is different (typing is more pleasant - hard to describe but it's clear when you compare them next to each other's), it has one more keyboard row, and I also like the fact that there is a color scheme: some keys pop out visually so it's easier to differentiate the keys compared to most keyboards nowadays where everything is black and boring.
