I've been tasked with a conversion of a collection of photographic images to vectors, and I'm trying to decide between the Illustrator CS6 and Corel Draw X7. Corel Draw X7 costs less than half what Adobe is charging for Illustrator CS6, and one can assume that in the foreseeable future, Corel will keep updating their product, whereas Adobe stopped updating the CS6 version and is steering any sales inquiries towards AI CC. AI CC subscription is offered at $20US a month, so one year of AI CC subscription cost almost as much as the perpetual copy of latest CD X7 ($319US at B&H Photo or $549CAD, currently on sale for $439CAD). Another difference is that Corel Draw X7 is actually a complete Graphics Suite, containing Paintshop, Web Creator, and number of other programs, while Adobe Illustrator is a dedicated vector drawing program. Since I own and am used to Photoshop, I wouldn't be using Paintshop Pro, although some of the other included programs might come handy.
I'm leaning towards CD, mainly because of its lower cost and straight forward future upgrade path. Apparently, both programs are similar in their functionality (Yes / No?) . AI CC has some extra features compared with AI CS6, but I am not sure how important they would be for this project.
How do these two products compare in terms of features, speed, and ease of use? Which one has better auto tracing capability and conversion of bitmaps to vector paths? Has anybody used both these products and what's your advice?
