As far as I am concerned this is the ONLY version of Batman v Superman: Dawn of Justice that exists. That other thing that Warner Bros. released in theatres is good but isn't a patch on what Snyder originally created. Snyder took an awful lot of flack for the theatrical release, but whatever you think about him as a film maker, you will have sympathy for him once you see how the studio took a hacksaw to his movie. This Ultimate Edition isn't simply another scene or two which adds 30 minutes but doesn't change the movie, it is a sprinkling of expansions to scenes throughout that solve its much maligned choppiness and lack of flow. Apart from the improved editing which allowed the film to breathe, this version of the movie makes you care about the characters more, especially Superman. Following the journey of Clarke Kent in more detail, seeing him actually do some investigative journalism, and understanding his motivations makes a huge difference. [spoiler] This is especially the case in his death at the end of the movie. Without earlier shots of him doing "Superman" things such as helping people after the Capitol Building bomb, as was the case in the theatrical release, I simply didn't care when he died. With the added tidbits in the Ultimate Edition, Supermans sacrifice brought me to floods of tears. Even though I knew what was coming, the gut punch was overpowering! [/spoiler] This character expansion also benefited his nemesis Lex Luthor, who with just a few additional scenes (that he isn't even necessarily in), transforms from a spoilt brat into a criminal mastermind. [spoiler] While it was previously suspected, it now becomes clear that he has his fingerprints on everything, from the Africa scene by blackmailing the witness, to intercepting Wallace Keefe's cheques from Bruce Wayne, and Keefe himself being an unknowing puppet of Luthor carrying a bomb in the led lined wheelchair so Superman couldn't see it. [/spoiler] Overall, my recommendation if you haven't seen Batman V Superman yet, or if you saw it in the theatres and hated it, is to give this version a watch. I loved it.
