Illustrator or photoshop/procreate?

I keep going back and forth and sort of just want to stick to one. I love drawing with photoshop and procreate cause it’s like pen to paper and I do a lot of illustrations. I also keep going back to illustrator cause something about the smoothness and vectors are satisfying. I don’t wanna keep going back and forth lol. I’m afraid of doing something and needing to scale it up later but also I guess I could just draw all my illustrations in bigger files so scaling up or down won’t be a problem.
