Although I own a license of Illustrator CS6, I no longer use it for work. When I do open it, I abuse it mostly as a conversion tool for AI files.
I never liked working in Illustrator: its basic workflow is cumbersome (this coming from an ex Adobe Certified Expert for Illustrator). I work with a Wacom tablet, and Illustrator's tiny handles and anchor points are quite painful to deal with on a 2560x1440 27" screen. Illustrator is also fiendishly slow compared to competing apps (although things have improved in CC 2014).
Also, I will NEVER subscribe to the CC model of Adobe. They lost me as a loyal ~18+ year long customer, and I switched to alternative software about 18 months ago.
So I prefer Xara Designer Pro, InkScape, and Photoline. Lately I tend to work more with Photoline's vector tools which got a boost in the latest beta. It just feels very convenient to be working with both vectors and excellent bitmap tools in the same application, and freely combining both in almost any way.
I worked with large level designs consisting of thousands of vector objects in Photoline, and quite like it. Honestly, the same levels in Illustrator were more difficult to manage.
So: good riddance Illustrator
PS one of the strengths of Photoline is its external app link: when I am working on a vector element in Photoline, and I need a quick edit in InkScape, Photoline allows me to quickly open that element in Inkscape, and then when I save the object in InkScape the object in Photoline is automatically updated. Very handy.
