Xbox One COD ghosts 720p

"Activision is now confirming that, yes, indeed, Call of Duty: Ghosts will run in 720p resolution on Xbox One, 1080p on PlayStation 4"

Am I going to notice a big difference here? I'm a huge xbox guy but now I'm starting to rethink getting the ONE. I have to have the best COD experience on a console here. What should I do? Get the ps4 or the xbox one?
