My current selection of vector illustration software at home is Macromedia Freehand MX, CorelDRAW 8, Fireworks MX 2004, Inkscape, and Serif DrawPlus X2. At work, I also have access to Adobe Illustrator CS2. Out of all of these, right now I prefer to use DrawPlus. I would use Fireworks, but it doesn't offer many file export formats, so vectors I create in Fireworks largely stay in Fireworks. Besides, since I'm working mostly with animating vectors right now, there's not much sense in creating shapes in one program just to export them to another, potentially losing something. The pen, shape and node editing tools in DrawPlus are good enough to do what I need, and I'm animating in DrawPlus anyway.
The first scene for one of my partially storyboarded animations is a title screen with an animated background, much like you'd see in most golden age video games. I drew the draft for the logo on a 3x5 index card about a week ago and used it as a reference when creating the final vector version in DrawPlus.
Here is the final DrawPlus vector, with a basic animated background. The final animation will not have this arbitrary pink and white flashing stuff, but rather a scrolling overhead view of a city. I opted not to add the emergency light over the "A" in the draft because I thought it added too much height to the otherwise vertically slim logo. "Emergent Deuce" is the name of this particular episode of Ambultax. I doubt there will be sequels, but you never know.
