3D with Cinema4D & Moi3D
2D with Adobe Designer CS4
I'm using Illustrator since Illustrator 3.
What I like in Illustrator : bezier curves, precision and basic tools (scale & deformation, rotate, move, duplicate, select tools, mask, patterns).
A lot of tools are ridiculous and I never use its.
Some of tools are good but could be better : gradient (cinema 4D has a very good gradient shader. Many types, easy to add colors with precision, many interpolations between colors, noise), effects (too much memory required), text on path is getting worth version after version.
What I hate : 32bits version (don't know about CC) crashes very often with huge files (imported pictures, multi-effects on shapes), no instances (master shape and clone shapes), no dimensioning tool (like plug Hot Door) and the new marketing politic. I don't want to be a gogo.
I hope Affinity would be an Illustrator killer.
First impressions are very positive : historic, snapping, effects on shapes, transform menu, layer effects, brushes with complex objects.
Interface is very clear and easy to understand.
Some basic functions are missed : we can't rotate or scale an object with a chosen point on the page, bézier curves are not easy to create (can't change the direction of only one vector), no text on curves.
But it's a very good job !
