I liked Cowboy Bebop as it was a more complete story. That is to say, there was an a lot more of it. You've got a full series that tells a complete story & a movie that only enhances that main series vs a series cut short before it's time with a good movie (Provided you liked the series) tacked on to try and end it.
And Bebop is the pinnacle of cool.
I enjoyed both & am patiently waiting for Hollywood to ruin BeBop for me.
