Logos using figure ground.

I discovered these logos by performing a google search using the terms: logo and figure ground.
The first logo was his previous attempt, the bottom logo is his "final" logo. 

I like the figure ground in this first logo  but I do not like the square top of the "J" it appears out of alignment and I keep seeing only the square; ignoring the "DJK" letters below. 

I prefer the logo above. The top of the "J"  is created using a colored circle, a perfect contrast to the more square shapes and black and white used elsewhere. The "J" centered gives you a focus point and draws you in.  The dot also adds a splash to a relatively conservative logo yet the logo can also work without the dot. In this logo, the letters are easily read without the top of the "J" pulling attention away from the DJK. It all seems to fit.
