Canned Or Bottled? Is There A Difference?

I have an ongoing friendly argument with a family member that says there IS a difference between canned sodas and bottled. I drink both all the time and I just don't think so. I don't taste a difference. 

Thoughts? No matter how many different ones I try, I have never been able to tell the difference. Do you think there is a difference in canned sodas and bottled sodas?
