Well, I've been reading ECJ since way back when it was in its original form (and paying occasional homage to my own strip (tee hee)), so I may also be biased. I'm flipping through all the oldies and admiring, in particular, the strips in the original style, but with all the cool shading.
The next style though, allowed for more expressive ... uh ... expressions, and I always liked the dots that everybody's nose makes when looked at head-on.
Even so, I prefer the original style, with the shading, over all the ones to come after. So there.
