PLU ML-87 is a tenkeyless keyboard, basically just your average mechanical design sans the number pad
pros:
- should be the least expensive of the bunch
- standard design and layout should require little to no learning curve and would be friendly for simple keycap replacement mods
cons:
- least number of features (examples below)
- might be only 2KRO
Noppoo Choc Mini is a compact tenkeyless board where it has most all the physical keys of a tenkeyless but they're just compacted in on the rest of the board so that its about a half row shorter and two rows narrower
pros:
- most features, for instance its a compact tenkeyless but it has the most dual-function keys, including a number pad and media keys
- arguably best overall product quality
- NKRO over USB
cons:
- least mod friendly, for instance replacing key caps (whether for look and/or feel) is one of the easiest mods yet the relatively unique compact layout (some keys are unique and others are reduced in size) of the Choc Mini as well as its dual function keys makes that more difficult to do than with a board like the PLU ML-87. Luckily key quality on the Mini is actually a major strength so this is less of a con overall, at least IMO... but I also think its one of the uglier keyboards because of some the secondary label color choices so its not a negligible con, again, at least IMO
KBC Poker is a 40% board where its basically just the main cluster of keys found on your average keyboard
pros:
- most compact/portable of the bunch
- very mod friendly (PCB mounted keys makes for easy switch/spring replacements or adding LED lights, and while PCB mounting might be less desirable due to keyboard flex it is also easily modded to reduce that effect)
cons:
- lack of physical keys might be a deal breaker for certain applications (particularly games) that make heavy use of those particular keys (F and arrow keys).
