I think, Photoshop for you it's better. In photoshop you can find some vector tools too (pen tool, shapes, primitives as box, circle etc). Also, you can use "smart object" tool for transformations as in illustrator and you can use this tool for pasting vector illustrator drawings. But in illustrator you will never make those things that you can make in photoshop... Other thing. Illustrator is very hard application...
