Old one was better
Don't get me wrong I like the old generative logo, but — is it really fit for purpose?
How you do you supply the logo to somebody else when requested? How does it deal with the sub-brands of the different departments? How do you deal with the general public not recognising different instances as "the same logo"?
Also, as much as I liked the generative one, it worked quite poorly at small sizes IMHO, and really sucked when pushed into B&W.
As a piece of art, and as an interesting experiment I like the old generative one.
As a piece of design fit for purpose — I much prefer the new one.
