Nothing wrong with CAD - it all depends on what you have (as BAJR said) and what you intend to do with the data. And these days it's easy enough to port linework between CAD and GIS, with a little forethought.
When digitising in CAD I prefer the "scan & trace" method these days, having got the T-shirt from years of calibrating tablets for digitising off the permatrace. You can zoom in on the scan for better accuracy, and of course it all takes up less room on the desk! In skilled hands there's very little difference in the time required, in my humble opinion...
