Ranked in these QuestionsQuestion Ranking
Pros

Pro Quiet
The Topre switches used on this keyboard allow for quiet typing.
Pro Great build quality
Probably the most well-built keyboard after the KUL-87

Pro Good feedback
The Topre switches are precision-tuned for each key, giving great feedback.

Pro Compact
Since there is no number pad, this keyboard takes up less space on the desk than typical keyboards.

Pro DIY
You can really make this board your own. The seperated space bar makes it even more fun than the regular Planck because you can program both space bars differently. You can also get the keys much more easily because you just need a pair of single key width keys.

Pro Split layout
You can set this board up in a very ergonomic manner
Cons
Con Characters difficult to read
With black character text printed on black keys, inscriptions can be difficult to read unless in a well lit room.

Con DIY
Most people just want to buy a keyboard so that they can have it and type on it. But if you're ordering an ortholinear 40% split keyboard, you've probably already got strong enough opinions on switches, key layouts, and keycaps, that you're not going to be very satisfied with a mass market keyboard anyway.

Con Somehow cheaper to spec out than a Planck
This keyboard is based on the Planck. You would think that the Planck, what with its popularity, would cost more. Somehow, it's actually cheaper. This actually has to do with the case/frame. Instead of ordering a really nice prefabricated case, you end up ordering laser cut panels and spacers to create a frame to hold the whole thing high enough off your desk to type comfortably.
