I've found that Anim8or is quick and easy to get into, and does some things very well, but it's not necessarily the most flexible program. For example, both Wings and Anim8or let you select vertices, edges, or polygons, and move them parallel to the X/Y/Z axes, but Anim8or defines those axes relative to the view. Wings lets you move a polygon in the direction of its normal, including a set of polygons each with their own normal. Essentially, that's how you could put a raised band around a sphere. I'm sure there are ways of doing that in Anim8or, but the nearest I've managed is a lot more awkward than in Wings. Wings can also be set up to cope with the very small object sizes required to match scale with Poser figures.
