and as always, before making a final decision, use the free trial versions of the apps, find the one that suits you. if may fits you better than any other, then use it, you can use your preffered tool for game development, specially for animation sequences, as it's the rendered animation that is going to be used, not the mesh. if it's to create the meshes for game models, most of the apps will export into most formats, so again, the specifc tool used isn't as important as how well you do the work. spending a few thousand to get an app, then finding that it's entire method of operations would be a waste of money, as if you work better with a lower priced app you only have to buy it.
