Horse manure. Wings is an OK modeller, and I used it for a while, but 1. there is absolutely nothing wrong with blender and 2. blender is more powerful, more effective, more professional, and easier than wings. Easier in the sense that one is more easily able to make exactly what he wants in a short amount of time with minimal errors and have a finer finished product than with wings.
Since I'm tired of this debate, if anyone would like to dispute this, I will have a timed contest with him. A full render would be preferrable but seeing as wings has no actual render engine, a modelling contest would be fine as well. Mechanical, organic, or otherwise.
