When i started, decades ago, the choice of graphic app was made based on what programs were used in our work.
The majority of agencies used Freehand. Illustrator was much more complicated. To start with, we could play around much more easily with Freehand without lessons.
I'm still missing some simple FH features...
Photoshop is the undisputed software for photo editing and CorelDraw vs Adobe Illustrator is a continuing debate over who is king. I have been using Corel and Illustrator since their early releases and to be hst, I use CorelDraw 80% of the time since it is so user friendly and intuitive.
I use both the same, once many uses them.
gotta have both! it's always good to have lots of tools in your toolbox ;)
Illustrator is much better for vector drawings and photoshop for image editing depends on what you will use but does not compare to Corel
I'm not a big fan of using many similar programs. It's better to stick to the you like and be really good with it.
Sure, having another similar program is good for precise operations or file conversions. I mean, it's nice to play a lot of instruments but you'll never master of them.
photoshop for raster images, and corel for more technical vector
Those days, the graphic/publishing world was on a Mac.
Of course today is a different thing but i never felt the need since then to change from FH or AI.
