What do you feel more comfortable using?
Neither, rarely used either one.
They are very attribute rich and don't simple things easily.
We often see a question like "which ONE program would I use/should I use/do pros use". But there's a big assumption here, and it's usually a wrong assumption. Pros use a mixture of programs to do their job. A common mixture, but by no means the only one, is
- (Sometimes) Word to get the text typed out without pictures or layout
- Photoshop, to manage photographs and scanned art
- Illustrator, to create original art on the computer
- InDesign to lay out pages, and put the text, photos, scanned art and original art together. (The text might be done in InDesign if there isn't much) To apply consistent styles so the thing looks professionally produced rather than a mish-mash.
Each of these programs would be used to save files in an organised systematic way before you bring things together. Copy/paste is hardly used.
These are professional tools and enormously rich in features; and diving in you are likely to make mistakes that lead you into bad results or needing to start the whole project again. I strongly recommend investing in serious training, not just in these programs but in the whole task of modern graphic design.
