Hi Guys, I wanted to post a few shots of these 2 boards I recently purchased. Mainly because I found relatively little information on the net about the Deck. Hopefully this helps anyone trying to pick between the two brands who are doing their own research
Models : Ducky Shine Zero Zone DK2108SZ with Cherry Blues and Deck Hassium (non pro) with Cherry Browns
Here you can see the height/profile is virtually identical. I would almost say they were the same OEM, however the Deck is MUCH heavier and solid :

Close up of keys and backlighting. You can see how much brighter the Ducky is compared to the Deck. I feel the Deck's PBT's keys do not allow as much light through as the Ducky's engraved ABS

Another shot to show you how much brighter the Ducky is :

Lights off :

I have found the Deck to be vastly superior in build quality. The finish, PBT keys, braided cable all add to that impression. Their is almost zero 'wiggle' when pressing the keys compared to the Ducky. I'm not sure if this is due to the thicker PBT construction. Its especially noticeable with the Spacebar for example. Strangely, I also like the font. But I'm definitely in the minority it seems
Probably the best thing going for the Ducky is the much higher brightness of the back lighting. But thats a personal preference.
Considering the prices are virtually identical (here is Australia) I would rate the Deck much higher.
Hopefully this little comparo helps someone out there! Let me know any questions.
