I have owned few custom, I will go from my least favorite to my most favorite
LZ-Alu skin - Pros - Has a thick acrylic plate, which gives a pretty nice typing experience imo.
- Nice colour.
- Price
Cons - Two aluminium skin with acrylic middle part "sandwich style", not a huge fan of that, especially the acrylic parts are all transparent.
- The aluminium finish is not smooth.
- Screws are screwed from top to bottom, which bother me a lot. And scratch my thumb sometimes.
LZ-CE - Pros - Huge variety of colour combination of case and colour bars.
- Cons - Boring design.
- Finish is not smooth.
GON NS 87 - Pros - Huge variety of colour.
- Awesome lighting with frosted acrylic middle part.
- Aluminium finish is very smooth.
Cons - Screws are screwed from top to bottom, but not too bad compare to LZ-Alu skin since GON NS 87 use hex screws.
- Sandwich style case.
- The feet are not close enough to the usb plug, so the whole keyboard would flip upside-down if pressing the top row too hard or cleaning the top row.
- Skinny case design. Some people like it, but I don't really like it.
LZ-F - Pros - The bar foot can flip around make the keyboard have two different angle .
- Smooth finish.
- The top part of the case cover the bottom of the case . Very good design imo, it can cover the little line(don't know what this called) where the top and bottom part intersect.
Picture of how the top part cover the bottom part:

Cons - The space above the function row and below the bottom row is much larger than the space of the side, kind of odd to me.
360Corsa - Pros - The design of the side is really really nice.
- Brass weight.
- Smooth finish.
- PCB mount to the top part of the case.
- Semi-glare, looks really nice under sun light.
- Cons - Angle, not a big fan of 8 degree.
- Don't really like the 360 logo above the cursor.
456GT - Pros - Nice brass weights design.
- The angle of the board is very nice and comfortable to type on. 12 degree iirc.
- Very smooth finish, even better than 360C imo.
- PCB mount to the top part of the case.
- Semi-glare, looks really nice under sun light.
- Available in PINK!
- Cons - The design of the side is little bit boring compare to 360C, but of course, 456GT is older.
Have never used or seen in real life, but I really really like the design of whale, the design of the side and back is just so nice.
Hope this information help you.
