I did most of the morphs for 3DCommune's new Alexa2 all with ZB2. For that alone it is a very valuable tool, but only scratches about 5% of ZB's potential. As far as using it alone and for modeling and texture, I'm a continual newbie all the way from version 0.95 ZB takes more time than I have to give it. It's become almost overwhelming with the number of features it has. There's more to remember when using ZB. You have to know what comes next a few steps ahead.
