I recently argued this same point with regards to Lightwave, and on reflection I think I was wrong.
GS undeniably has it's frustrations, but then I've seen a lot of cool stuff created with it.
I like it, but then I haven't realy disliked any of the apps I've tried this year (Carrara, Lightwave, GS, Hexagon, Shade, Poser, Fragmo). They all have something going for them.
At the moment I'm using Hex for modelling and texturing, and I'm using Poser for animations, and blending them in Fragmo. Some people would hate doing this, but it doesn't faze me.
