I have a Wacom tablet, but I seldom use it anymore. After 2 weeks of trying to get used to it, I found that a mouse works better. IMO, if you use "painter" softwares and paint something from scratch, then a tablet is a must, because wou will really need the "pressure" sensitive effects. But if you will just trace something from a scanned image, a mouse and your Bezier tool (& other drawing tools) would be easier to use. Even for embroidery digitizing jobs, I still find the mouse easier to use.
