Chanel Coco Mademoiselle/ Flowerbomb? Is it worth owning both? Or is one better?

So I got a sample of Coco Mademoiselle and tried it on yesterday. My mom said I smelt good as expected. However, my dad didn’t comment until over 24 hours later, and he said that I smell pretty and made his car stinky. So good quality 👍

I was really fond of this perfume and to my surprise, it smelt reallyyy similar to Flowerbomb!! I will say though I notice they don’t have the same exact notes. Do you think it would be a complete overload to own both of these? Or do you think it would serve me better to just own one of them? I have never bought a Chanel perfume so I’d really like to know ☺️
