Inkscape is great, but Illustrator is still my choice for vector design: Here’s why
See my reasons for choosing Adobe Illustrator over Inkscape.

If I need to design a vector graphic from scratch, beyond grabbing a pad of paper and pencil to draw my idea first, I’ll always gravitate directly to Adobe Illustrator. Illustrator is a native vector design tool, allowing you to seamlessly create vectors in an environment suited for it, rather than trying to design vectors in a raster-based environmentlike Photoshop.
