I personally liked Outlaw Star more than Cowboy Beebop. I say this because to me, Outlaw Star has more style to it than Cowboy Beebop. More colors, more interesting ships and sci-fi action, cooler character design. Also, the characters are much more distinct amongst each other. And there isn't as much filler. Don't get me wrong.Cowboy Beebop is a modern classic that was one of the front-runners of the anime explosion of the 90's. But Outlaw Star was much more interesting.
