I prefer Illustrator or even CorelDRAW both are more complete than Inkscape but sometimes if you work as a professional and have to buy a license you have to choose the cheapest one , in this case Inkscape!
I prefer Illustrator
I've got to add a bit here.......I'm from back in the days of micrographix designer and pagemaker. Shortly afterwards I started with Coreldraw. I didn't like Corel at first, but my employer at the time demanded it be used. So I did,,,and I learned. Today I'm still using and sometimes preferring Coreldraw to Illustrator. But somehow I usually end up using them BOTH in projects. They've both got ups and downs, I'd have to admit that Illustrator has that total air of professionality to it that you just "feel" as you drive it, but Corel is fast and efficient to work with. Illustrator wins hands down as far as handling color. :-)
I absolutely prefer Illustrator. But if you find that Illustrator is a little bit too expensive, Inkspace isn't bad choice, either.
illy. for sure.
No idea what the other program is, I've always used Illustrator.
depends on the base os, if only linux based then prolly inkscape however the learning curve is difficult comming from adobe suite, now on osx and win ai is the best tool imo, the only problem is that illustrator is for illustrating, failing to understand that and trying to design something more demanding like a book or something with more precision can make ai the worst, since rendering type is not the strong point on it, cant say for inkscape on this, as a designer i dont marry with tools i just pick whichever suits my needs or offers performance
Illustrator of course !!!
inkscape its cool and free, but there is an only way for vectors based design: Illustrator!
I agree with everyone else above, Illustrator is definitely the way to go!
