I don't use AI. I have it if all else fails. As all signs shops should.
I'm merely adding to the great debate as requested by the orig post. Corel vs. Illustrator
No one will ever convince me that Adobe is better than Corel. I have yet to find a design that cannot be done in Corel.
The only way that one is really better the the other is due to what the user can do in the most efficient manner for themselves given the product by themselves.
As far creating vectors and the various effects therein, I would say that parity is very very close as far as vector creation goes. How they achieve it and what they allow the user to customize may or may not be different in certain areas. Some people might do better with a program doing it this way, some do better with a problem that does it that way. A lot of the time, it's just what they are used to.
I
hated, absolutely
hated DRAW and it was bundled with my main digitizing program and I have several thousand reasons to have it easier for me to use DRAW compared to Ai due to it's tighter integration. Now, I'm in no way saying that DRAW is inferior when it comes to vector creation (I can make Inkscape do exactly everything that I need to do and I have a Python script that allows me to spit out embroidery files as well, that to me is far more customization then what you are talking about), but how it does things doesn't go well with how I like to do things.
Further evidence that it's going to depend on the person (at least as far as I'm concerned), the issues that you bring about, while I have no doubt are important to your workflow, they don't affect me in the same way. Therefore the advantage that you have with DRAW over Ai doesn't exactly do the same thing for me.
So really, like with any tool, the only real way that one is better then the other depends on the person wielding the tool.
