In my opinion, Re: Coded and 358/2 Days are complete opposites of each other.
358/2 Days had a great story, but the gameplay was bad, and Re: Coded had a forgettable story, but the gameplay was actually fun.
I think Re: Coded had the best Command deck in the series, next to BBS.
It's up to you, but if I were you, I would just watch the cinematics on the HD Collections.
