Using CorelDraw at work and have Illustrator at home, but it's extremely confusing working with both. Especially as i am still a bloody beginner and don't know many things or how to get this or that done yet. But maybe one day
For these I used photoshop for the vector elements. Didn't make it in to illustrator at all. But you're right. Switching back and forth can be really confusing. Might be best to give up on one. If you have to use one for work, it might be better to learn that one.
