Ditto.
Frankly, I can't understand the current trend of 'tracing-phobia'. Even tracing implies a good amount of effort and artistry.
On the one hand, I think EvaKiss' game is more polished and s/he is a more accomplished storyteller. The level of replayability of GGGB is still unbeated (imho - and it was so also in v0.1), even though the story in itself is really basic.
On the other hand, I think Echidna is more comfortable with drawings, especially for face expressions. His game is simpler and yet effective. It feels more urgent (or, one can say, more 'ecchi'!), so maybe there would be a pacing problem in the future, who knows.
At any rate, they currently are - along with Jessica O'Neal - among my favorite VNs
